What to do if there is no . Sound not working on computer

The computer's sound system is closely related to drivers. Therefore, if you have any problems with sound playback, then you should not immediately panic - it is quite possible that an ordinary user can fix the error. Today we will look at several different situations when the sound has disappeared on the computer.

There are many reasons why sound may disappear on a PC. As a rule, this is either a hardware problem or a driver conflict with other programs. In this article, we will analyze what the problem may be and try to restore the sound.

Reason 1: Speakers disabled

First of all, check that the speakers are really connected to the computer. It often happens when the user simply forgot to connect them with a cord or did it wrong.

Attention!
There are completely different types of connectors on a sound card. But you need to find the exit covered in green and connect the device through it.

It is also worth making sure that the switch on the speakers themselves is in the working position and the volume control is not turned all the way counterclockwise. If you are sure that the device is still connected and working, then proceed to the next step.

Reason 2: Sound off

One of the most commonplace reasons for the lack of sound is reducing it to a minimum in the system or on the device itself. Therefore, first of all, turn the volume control on the speakers clockwise, and also click on the speaker icon in the tray to change the volume.

Reason 3: Missing drivers

Another common reason for the lack of sound on the device is incorrectly selected drivers or even their absence. In this case, the system cannot normally interact with the audio subsystem and problems arise, the result of which we are trying to fix.

You can check if there are drivers for sound equipment in "Device Manager". Open it in any known way (for example, through "Properties of the system", which can be opened by right-clicking on the shortcut "My computer") and make sure in the tabs "Audio inputs and outputs", as well as "Sound, game and video devices" no unknown devices. If there are any, this indicates that the necessary software is missing.

You can select drivers manually on the official website of the laptop or speaker manufacturer and this will be the most reliable way to find the right software. You can also use special universal programs or find the software using the speaker ID. Below we have left a few links that tell you how to do this:

Reason 4: Wrong playback device selected

Another common problem that can occur if third-party audio playback devices are or have been connected to the computer is that the computer is simply trying to play sound through another, possibly disconnected, device. To fix this, follow the instructions below:

By the way, for this reason, a situation may arise when headphones are connected to the computer, and the sound is still broadcast through the main speakers. Therefore, do not forget to check which playback device is selected as the main one. Other reasons why headphones may not work can be found in the following article:

Reason 5: Audio codecs are missing

If you hear a sound when Windows startup, but it is not there while playing a video or audio recording, then most likely the problem lies in the lack of codecs (or the problem is in the player itself). In this case, you need to install special software (and also remove the old one, if it was). We recommend installing the most popular and proven set of codecs - which will allow you to play video and audio of any format, as well as install a fast and convenient player.

Reason 6: Wrong BIOS setting

It is possible that you have a sound device disabled in your BIOS. To check this, you need to go into the BIOS. Entering the required menu on each laptop and computer is carried out in different ways, but most often it is a keystroke F2 or Delete during device boot. On our website you will find a whole section devoted to ways to enter BIOS from various laptops.

When you get to the required settings, look for an option that may contain the words sound, Audio, HDA and others related to sound. Depending on the BIOS version, it may be in sections "Advanced" or "Integrated Peripherals". Opposite the found item, you need to set the values "Enabled"(Enabled) or Auto(Automatically). Thus, you will connect the speakers in the BIOS and, most likely, you will be able to listen to audio files again.

Reason 7: Speaker failure

One of the worst scenarios is the breakdown of the playback device. Try connecting your speakers to another PC to see if they work. If the sound does not appear, try changing the cord with which you connected them. If you still can’t hear anything, then we can’t help you and we recommend contacting a service center. By the way, you can only check the laptop speakers with specialists.

Reason 8: Driver corruption

Also, the sound may disappear as a result of damage to the audio driver. This can happen after installing or uninstalling a program, updating Windows, or as a result of a virus attack. In this case, you must uninstall the old software and install the new one.

To uninstall non-working software, go to "Device Manager" with help Windows + X menu and remove your audio equipment from the list by right-clicking on it and selecting the appropriate line from the context menu. At uninstalling Windows will prompt the user to erase and secure this device.

Now you just have to install the new software as described in the third paragraph of this article.

Reason 9: Viral Infection

You can consider the option that your PC has undergone some kind of virus attack, as a result of which the sound drivers have been damaged. In this case, you should scan your computer for virus software as soon as possible and remove all suspicious files. You can do this with any antivirus. There is a whole section on our website where you can find reviews of the most popular products for preventing infection of the device, as well as cleaning it. Just follow the link below.

Problems with functionality PCs can occur for a variety of reasons. At the same time, there are many solutions to solve a particular problem. But recently, many users are increasingly looking for search engines articles with a request: no sound on computer what to do in a similar situation?

Consider 10 reasons that directly affect sound reproduction.

The sound may not be played for a banal reason: the volume slider is at a minimum or even at 0. Click on the speaker icon located in the tray and make sure that the volume level is not set to the minimum.

Also, you can immediately pay attention to the button located at the bottom of the slider. It allows you to completely turn off the sound. Perhaps this is the reason, because even if the volume level is at the maximum, there will be no sound coming from the playback devices.

There may also be playback problems in one or more specific programs. In this case, you need to open the volume mixer and also move the slider from the minimum.

Do not forget also that if your headphones are connected through speakers, playback will only be in them, and nothing will sound from the speakers.

Setting playback devices

If there are several playback devices connected to the computer, the problem may be that the specific speakers are not selected as the “default” device. To do this, right-click on the same speaker icon and select the "Playback devices" line.

Carefully examine the list of displayed devices and make sure that the speakers show a green checkmark, indicating that this device is used by default.

If there is no check mark, right-click on the speakers (or on another device that should act as playback equipment) and click on the "Set as default" line.

If the speaker icon is displayed in black and white, this means that the device is turned off. To enable it, you also need to right-click and click on the enable item.

If the required device is not in the provided list, you need to enable the display of all disconnected devices. To do this, right-click on any free space and check the box "Show disabled devices", after which they can be enabled and set as the default device.

Sound card health check

If the sound is still not playing, you need to check if the sound card is turned on? To do this, right-click on "My Computer", then click on "Management" and select "Device Manager".

Expand the Sound Devices menu and make sure your sound card is enabled. If this is not the case (the down arrow is displayed on the icon), right-click and select the "Enable" line.

If there are no sound devices in the list at all, find the “Other devices” item, where, most likely, in this case, the device you are looking for will be displayed, but without installed (outdated) drivers.

Driver installation is discussed in the next paragraph.

Installing the sound driver

The most appropriate way is to automatically search for the driver. To do this, right-click on the device and click "Update Drivers", then select automatic search. If the system finds a suitable one, it will automatically install it and you will only have to wait. If the search was unsuccessful, it must be downloaded from the official website. To do this, you need to know the full labeling sound card. It can be found in the documentation this device, or use the special AIDA64 application, which will present a list of all connected devices.

Having received the full name of the sound card, look on the official website latest version driver for your operating system and download it.

Right click on the unknown device again and search directly on your PC.

In the search folder selection field, enter the address where you downloaded the driver.

After that, the installation will start.

Note: For Realtek audio cards, you can download the Realtek High Definition Audio Driver, which will help you not only restore sound, but also easily connect other devices, such as a microphone, in a special application window.

To open this window, just click on the icon in the tray (shown in the screenshot).

If the drivers were previously installed, but there is no sound, you need to update the drivers. To do this, right-click on the speaker icon in the device manager and open the "Properties" item, then, in the driver tab, click on the "Update" button.

Checking the physical connection of the speakers to the computer

Rotate the system unit so that you can clearly see all the connected wires. Make sure the speaker connection is stable and firmly fixed in the jack. Also pay attention to which connector the plug is inserted into, because, in 99% of cases, it should be connected to the green connector.

Enable the Windows Audio Service

Sometimes, after critical failures, some services are disabled, including the one that is responsible for playing sound. To restart it, follow these steps:

• press the Win + R combination and enter services.msc in the window that appears;

• look for the Windows Audio service and make sure the Status column shows "Running". If so, the window can be closed, but if not, the service must be restarted. Click on it RMB, and then "Properties";

• in the "Startup type" field, set the value to "Automatic", then "Start";

• save your changes.

Checking the performance of playback devices

It is clear that you have probably already checked the speakers or headphones, but still, connect them to another computer, TV, player to make sure that they work. If there is no sound when connecting to other devices, then the problem is with the speakers (headphones).

BIOS setup

If you changed the BIOS settings, you could accidentally touch the sound settings, disabling playback. Find the High Device Configuration line in the Advanced tab and if it is not set to Enabled, do it.

virus attack

And although viruses rarely affect services, sound drivers, you also need to check this. Perform a system scan with an antivirus program and, if found, remove any malicious files. Next, you will have to go back and start checking from the first point.

Restoring or reinstalling the OS

This extreme step can only be used if you have lost sound at a certain moment (day). This could happen, for example, due to an OS update. Open the "System Restore" window and select the date of the restoration, when exactly the sound worked for you.

If none of the mentioned solutions helped in restoring the sound, it is most likely that your audio card is broken and in this case without service center Or buying a new one is out of the question.

In contact with

It's hard to imagine a more ridiculous situation than watching the next issue of Comedy club on PC without sound. However, this kind of computer malfunction is far from uncommon in user practice. A great example of this is the irrepressible popularity of questions about how to turn on sound on a computer. Yes, your PC's "unauthorized boycott" is definitely a nasty surprise for many novice users. Especially when you consider that the problem with sound is very multifaceted in resolution. However, you, dear reader, are lucky again! Because in just a few minutes you will be able to "unlock" almost any Windows operating system. Well, let's not waste precious time - let's turn to the experience of professionals.

Diagnosis of computer "dumbness"

The answer to the question of how to restore sound on a computer must be sought in two directions. The fact is that most often the system "loses its voice" due to software failures. However, the sound may disappear as a result of the failure of any hardware component. For example, an integrated audio chip. To understand what exactly is the cause of "silence", you need to resort to step by step plan actions. Only after a thorough, practical analysis will you be sure what type of audio malfunction you have: hardware or software. However, let's not talk about the bad - everything should be decided without the intervention of a specialist.

Step number 1. Elementary check

Tell me how to turn on the sound on the computer if the speakers are inoperative or simply not connected? Of course, no way! Exceptionally simple steps will help you avoid mistakes and wasted time.

First of all, you need to check:

• Whether the speakers are connected to the PC and whether the jack used matches the destination device.
• The location of the plug if the speakers are powered from an electrical outlet.
• What position is the volume control in? Perhaps it is twisted "to zero".
• Is one of the connecting cords damaged?

Often it is these “platitudes” that push a person to the wrong actions. Therefore, be careful. Connect speakers that you know are working. Perhaps all your fears are in vain!

Step #2. Find "secret" signs

In the event that the sound on the computer has disappeared, pay attention to the speaker icon located in the system tray. Perhaps it is crossed out, which means that the playback device is deactivated. Move the slider up. If everything remains the same, move on to the next decision point.

Step #3. Windows Services

It's no secret that the operating system has an incredibly wide functionality. Management and control in the OS is carried out by special services, one of which is responsible for playing audio material. A complete sound setup on a computer without the participation of Windows Audio is simply impossible. Therefore, it is necessary to check the current status of this service.

• Use the Win+R hotkey combination to bring up the Run menu.
• In the window that opens, enter the services.msc command. After confirming with the "OK" button, you will be redirected to a special section "Services".
• Find Windows Audio in the list provided.

In order for the sound to play and the audio settings to be correctly recognized by the system, you must make sure that the service is active. That is, the “Status” column indicates the “Running” parameter, and the “Startup type” column is set to “Automatic”. You can make the necessary changes using the same right mouse button by placing the cursor on the item that requires the appropriate revision.

Step #4. A driver that can "fly out"

The crossed-out speaker in the tray can also indicate the incapacity of the special program code that controls the audio chip. In other words, the sound on the computer disappears when the driver becomes inoperative.

• Open the start menu.
• Then go to the "System" section.
• Select "Device Manager" on the left side of the window.

It will not be difficult for you to find the “culprit” of a problematic situation. In the presented list, a non-working device will be marked with an exclamation or prohibition sign. Update the sound driver using the service disk (software for the motherboard included). In the absence of such, you need to contact the official website of the manufacturer and in the "Support" section download the software tool corresponding to the modification of your PC. It is worth noting that before installing the latest version of the sound driver, you must uninstall the old device management component.

Standard Windows functionality

When all your practical attempts to answer the question of how to turn on the sound on your computer have not brought fruitful results, it makes sense to use the incredibly convenient Troubleshooting option. However, this functionality is only available in later versions. operating system Windows. To run this conflict resolution tool, you need to right-click on the conflicting device (indicated by the system with a special warning sign) and select "Diagnostics and repair" in the context menu. After a few minutes, the OS will notify you of the result of the work done. It is likely that such a sound setting on the computer will be an effective salvation, it would seem, "deaf" situation.

Step #5: Settings

If you are convinced that the driver is installed correctly, and the service window of the sound device "Properties" displays the current state of "Working normally", then the solution to the question "how to turn on the sound on the computer" should be searched for by the following algorithm of actions:

• From the Start menu, select Control Panel.
• Go to the "Sound" section.
• In the window that opens, right-click on the icon of the displayed playback device. Select "Properties" from the context menu.
• While on the "General" tab, pay attention to the item "Device use" below. More precisely, on the value in the checkbox. Apply the On option.

In the case when there are several installed playback devices in the mentioned list, one of them should be assigned the value "Default".

Step #6 Audio Controller

As a rule, most of the manufactured motherboards have an extended sound scheme. That is, the integrated audio chip can be controlled by a specially installed driver. Let's look at an example where sound settings on a computer are carried out using the Realtek HD Manager.

• Click on the speaker icon (darker in color and slightly larger than the standard Windows volume control).
• In the opened working window of the dispatcher, you need to activate the icon in the form of a wrench (lower part of the interface, on the right).
• In the case when sound is not reproduced, it is necessary to change the scheme from one value to another (meaning "AC front panel" 97 and the item of the same name, located just below).

Often it is this change that allows you to use the desired audio channel.

Step #7: Weird Media Format

There are often cases when sound playback on a computer is impossible due to a missing audio codec. This difficulty can be easily corrected.

• Enter in the search bar of the browser K-Lite Codec Pack.
• Then select the official source of the product from the list provided.
• Download and install the required software.

Typically, this action gives the PC an "omnivorous" multimedia capability. Be sure: your computer will not be an exception to the rule.

Step number 8. Software incidents

It happens that after installing a certain software, the sound disappears, and after uninstalling the conflicting program, it reappears. Some multimedia players play a limited number of audio and video formats. This is the only reason why unlucky users often start to panic. Therefore, before installing any program for viewing and playing multimedia content, you should refer to product reviews and an overview of its tactical and technical capabilities.

Step number 9. Look for the reason in the BIOS

As you know, the BIOS firmware manages and controls the operation of the entire hardware of a computing device. So installing sound on a computer can turn out to be an impossible mission when the audio functionality is disabled in the BIOS for some unknown reason. However, knowing the main rule when working with the base system: “Do not touch or change unknown values”, you will successfully cope with the task.

To check if the audio function is enabled in the BIOS, you must do the following:

• Enter the Bios of your PC.
• Depending on the BSVV version, the location of the sound “switch” may vary. However, the name "AUDIO" and the value "Enabled/Disabled" or "On" are unchanged.
• Finding the tab with the option Onboard Device Configuration, or High Definition Audio, is not difficult. The main thing is to understand the seriousness of the enterprise and not to make rash changes to the firmware. Because it's risky...

Step #10 System Restore

If, after all the manipulations, the question of how to install sound on a computer remains unresolved, then it would be prudent to use the method presented below.

• Go to the start menu.
• Enter "recovery" in the search bar.
• After the desired section is displayed at the top of the service window, press Enter.
• Select the required backup and confirm your choice with the corresponding key.

After the reboot, the system will regain the ability to play sound.

Step #11Corrupted or Missing OS Files

Sometimes the question of how to make sound on a computer is solved by restoring lost entries in the system registry. After all, very often the user, as a result of erroneous actions (usually this happens in pursuit of free space on the hard disk), deletes important OS data. Ultimately, the inevitable happens - Windows loses its full functionality. However, the unfortunate user does not always have the opportunity to roll back the system to its original state. By the way, the same well-known reason is to blame for everything - saving space on the HDD, that is, there are simply no backup copies of the OS, since System Restore is purposefully disabled. Nevertheless, even in such a situation, there is a way out.

• Press the Win and R keys at the same time.
• In the Run menu, type cmd.exe
• · Type sfc /scannow in the command window.
• Press Enter.

The damaged data will be restored from the backup storage. It is likely that after rebooting the OS, you will hear the audio greeting again.

Step #12 Virus Infection

Malicious code doesn't just steal and destroy user data. A virus program, having infiltrated the operating system environment, can also be the reason that the sound on the computer has disappeared. In order to identify the pest, you need special software. Often, the traditionally used anti-virus program for protection is not quite enough. However, today there are plenty of effective malware killers on the Internet. Therefore, you should not have any particular difficulties in the process of finding the necessary software.

• To ensure that your PC never has sound problems, periodically check on the official website of your manufacturer (motherboard manufacturer) for more recent driver versions.
• When connecting devices for audio playback to the PC system connectors, it will not be superfluous to understand in more detail the correctness of the connection scheme involved.
• Often motherboards have special pads that can be closed with special jumpers in order to reassign the audio output. Therefore, it is worth referring to the motherboard documentation and studying the problematic issue in more detail.
• If all methods are in vain in terms of your expectations (which is unlikely to happen), seek specialized help.

How to connect sound on a computer? As you can imagine, this is an incredibly broad question. However, today you have learned a lot of information about what needs to be done in order to "talk" your electronic friend, and what you should be wary of during its operation. All the best to you and pleasant sound impressions!

The computer has long ceased to be exclusively an apparatus for work and calculations. Many users use it for entertainment purposes: watching movies, listening to music, playing games. In addition, using a PC, you can communicate with other users and learn. Yes, and some users work better with musical accompaniment. But when using a computer, you may encounter such a problem as the lack of sound. Let's see how it can be caused and how to solve it on a laptop or desktop PC with Windows 7.

The loss of sound on a PC can be caused by various circumstances, but all of them can be divided into 4 groups:

• Acoustic system (speakers, headphones, etc.);
• PC hardware;
• Operating system;
• Applications that play sound.

The last group of factors will not be considered in this article, since this is a problem of a specific program, and not of the system as a whole. We will focus on solving complex problems with sound.

In addition, it should be noted that the sound may disappear, both due to various breakdowns and failures, and due to incorrect settings of serviceable components.

Method 1: speaker system malfunctions

One of the common reasons why a computer does not reproduce sound is problems with connected acoustics (headphones, speakers, etc.).

1. First of all, do the following verification:
   • is the speaker system connected to the computer correctly;
   • whether the plug is connected to the power supply (if such a possibility is provided);
   • whether the sound device itself is turned on;
   • whether the volume control on the acoustics is set to the “0” position.
2. If there is such an opportunity, then check the performance of the speaker system on another device. If you are using a laptop with headphones or speakers connected, check how the sound is reproduced by the built-in speakers of this computing device.
3. If the result is negative and the speaker system does not work, then you need to contact a qualified master or simply replace it with a new one. If it reproduces sound normally on other devices, then it means that it is not a matter of acoustics and we move on to the next options for solving the problem.

Method 2: Icon on the taskbar

Before looking for malfunctions in the system, it makes sense to check if the sound on the computer is turned off with standard tools.

But a situation is possible when the crossed out circle is absent, but there is still no sound.

There is also an option when an icon in the form of a crossed-out circle is present at the same time and the volume control is lowered to the limit down. In this case, you need to alternately carry out both of the above manipulations.

Method 3: drivers

Sometimes the missing sound on a PC can be caused by a problem with the drivers. They may be incorrectly installed or missing altogether. Of course, it's best to reinstall the driver from the disc that came with the sound card installed in your computer. To do this, you need to insert the disc into the drive and, after starting it, follow the recommendations that appear on the screen. But if for some reason you do not have a disk, then we adhere to the following recommendations.

1. Click "Start". Next, move to "Control Panel".



2. Move across "System and safety".



3. Further in the section "System" go to subsection "Device Manager".

   

   You can also make the transition to the Device Manager by entering a command in the tool field "Run". We call the window "Run" (Win+R). We enter the command:

   Click OK.



4. The Device Manager window launches. Click on the category name "Sound, video and gaming devices".



5. A list will appear containing the name of the sound card that is installed in your PC. Right click on it and select from the list "Update Drivers...".



6. A window is launched that prompts you to choose how to update the driver: perform an automatic search on the Internet or specify the path to a pre-downloaded driver located on the PC's hard drive. Choose an option "Automatically search for updated drivers".



7. The process starts automatic search online drivers.



8. If updates are found, they can be installed immediately.

If the computer fails to detect updates automatically, then you can manually search for drivers via the Internet.

1. To do this, simply open a browser and type in the name of the sound card installed on your computer into the search engine. Then, from the search results, go to the sound card manufacturer's web resource and download the necessary updates to your PC.

   

   If there is an exclamation mark next to the name of the sound equipment in the Device Manager, then this means that it does not work correctly.

   
   

   Method 4: Enable the service

   There may be no sound on the computer for the reason that the service responsible for playing it is disabled. Let's find out how to enable it on Windows 7.

   1. In order to check the health of the service and, if necessary, enable it, you should go to the Service Manager. For this we click "Start". Next click "Control Panel".

   

   2. In the window that opens, click "System and safety".

   

   3. Next, go to the point "Administration".

   

   4. A list of tools is displayed. Stop your choice on the name "Services".

      

      You can also open the Service Manager in another way. Dial Win+R. A window will open "Run". Enter:

      Click OK.

   

   5. In the drop-down list, find the component called Windows Audio. If in the field "Startup Type" worth the value "Disabled", but not "Works", then this means that the reason for the lack of sound lies precisely in the stop of the service.

   

   6. Double-click on the component name to go to its properties.

   

   7. In the window that opens, in the section "General" make sure that in the field "Startup Type" definitely an option "Automatically". If another value is set there, then click on the field and select the required option from the drop-down list. If you do not do this, then after restarting the computer, you will notice that the sound disappears again and the service will again have to be started manually. Next, press the button OK.

   

   8. After returning to the Service Manager, re-highlight Windows Audio and in the left part of the window, click on "Run".

   

   9. The service start process is in progress.

   

   10. After that, the service will start working, as indicated by the attribute "Works" in field "State". Also note that in the field "Startup Type" value has been set "Automatically".

   

   After completing these steps, the sound on the computer should appear.

   Method 5: Check for viruses

   One of the reasons why the computer does not play sound may be a virus infection.

   As practice shows, if the virus has already made its way to the computer, then scanning the system with a regular antivirus is ineffective. In this case, a special anti-virus utility with scanning and disinfection functions, for example, can help. Moreover, it is better to scan from another device, after connecting it to a PC, regarding which there are suspicions of infection. As a last resort, if it is not possible to scan from another device, use removable media to complete the procedure.

   

   During the scanning procedure, follow the recommendations that the anti-virus utility will give.

   Even if you can successfully eliminate the malicious code, sound recovery is not yet guaranteed, as the virus could damage drivers or important system files. In this case, it is necessary to reinstall the drivers, and, if necessary, perform a system restore.

   Method 6: Recovery and reinstallation of the OS

   If none of the described methods gave a positive result and you made sure that the cause of the problem is not acoustics, it makes sense to restore the system from or roll back to the previously created one. It is important that the backup and restore point is created before the audio problems start, not after.

   
   

   

   If your computer does not have a system restore point created before the sound crashed, and there is no removable media with a backup, then in this case you will have to reinstall the OS.

   Method 7: Sound card malfunction

   If you exactly followed all the recommendations described above, but even after reinstalling the operating system, the sound did not appear, then in this case, with a high degree of probability, we can say that the problem is a malfunction of one of the hardware components of the computer. Most likely, the lack of sound is caused by a broken sound card.

   In this case, you must either seek help from a specialist, or replace the faulty sound card yourself. Before replacing, you can first test the sound element of your computer by connecting it to another PC.

   As you can see, there are a lot of reasons why on a computer under Windows control 7 sound may be lost. Before you begin to fix the problem, it is better to find out the immediate cause. If this cannot be done immediately, then try to apply various options for correcting the situation, according to the algorithm given in this article, and then check if the sound has appeared. The most radical options (reinstalling the OS and replacing the sound card) should be done as a last resort, if other methods have not helped.

Knowing about all the possible problems associated with sound in Windows, you can easily determine why the sound is not working and immediately fix it.

To do this, you do not need any additional hardware or software. Most sound problems are fixed with a pair of straight hands and standard Windows software.

Causes and remedies

The cause of sound problems can be either an incorrect volume control on the speaker or a failure of the sound card.

All causes of sound problems can be divided into 3 groups:

Problems with sound-reproducing equipment are solved by its simple diagnostics:

1. checking connections with the computer;
2. network;
3. hardware volume controls.

Hardware problems are solved by repairing, checking the connection, or replacing the sound card. And if only the master can repair the sound board, then check the connections, and also replace the board with a new one, which is also within the power of an ordinary user. To do this, you need to understand a little about the device of the computer.

Problems with software- these are the most common problems with sound. They arise as, due to improper configuration or installation of sound drivers, system utilities, or individual applications.

Determining the cause of a software problem is the most difficult task, but it can be completely solved with a competent approach and sequence of actions. Such problems are corrected by reconfiguring the software, reinstalling drivers, and in some cases, performing a system restore or reinstallation.

Video: what to do if the speakers do not work

No sound on

Sometimes the reason for the lack of sound is not related to problems, but to the fact that the sound is simply turned off, and we all wonder: why does the sound not work for me?

On a computer with an operating systemWindowssound control is done:

1. on a sound reproducing device;
2. in Windows system settings;
3. in the utility settings for the sound card driver;
4. in the settings of a specific program.

If there is no sound on your computer, you should first check the hardware volume control on the speaker system, speakers or headphones.

For this you need:

• open the folder with standard audio recordings;
• enable playback of one of them by a standard player, such as Windows media.

Such a sound recording, when the system is working properly, should be played “out of the box”, that is, by standard pre-installed software of the operating system without installing additional software. That is, if everything is in order with the system itself and with the speakers, the sound should be played.

In all operating systems of the Windows family up to and including XP, the folder with standard audio recordings is called "my music", and is located in the "My Documents" directory.

O t "seven" and older, this folder is called "music samples". And it is located in the directories: "system disk" "users" - "general" - "general music".

On the sound reproducing device itself, you need to check the position of the volume control, the connection of the device itself to the electrical network and to the computer. There may be a power button on the speakers themselves, the inclusion of which should also be checked.

Important: The connector for connecting speakers to a computer, as a rule, also fits other connectors on a sound card. But the sound will only work if the plug is connected to the correct jack. On a sound card, such a connector is usually marked with a speaker image, and is green, like most speaker and speaker plugs.

If after checking the speakers there is no sound, you can test them for operability with another sound source, such as a DVD player.

You should also check the sound performance with other speakers or headphones. If, after the above steps, the sound appears, the speakers should be replaced or repaired. If there is still no sound, the problem is something else.

Missing or incorrect drivers

If there is no sound in the computer, suspicion falls, primarily on the driver.

After all, the sound will be absent if:

• the driver is not installed;
• an outdated version of the driver is installed;
• The driver is not compatible with the device.

Modern operating systems of the Windows family have a built-in standard audio driver that is compatible with most known sound cards. Older operating systems do not have such standard drivers, and some sound cards are not supported by standard operating system drivers.

Therefore, if you have a clean modern operating system installed, but it does not play sound, you need to use special drivers for the sound card.

Such drivers are usually supplied on a CD with the sound card.

If there were no such disks or they are lost, the drivers can be downloaded from:

1. official website of the sound card manufacturer;
2. official website of the laptop manufacturer.

Information about the manufacturer of the sound card can be found:

If the passport to the computer is lost, and nothing is indicated on the sound card itself, you can use the special Everest utility, a trial version of which can be downloaded for free on the Internet. This utility allows you to get information about the manufacturer and model of any part of the computer, from the usb node to the processor.

If you do not know whether the driver is installed or not, and whether the driver works properly, you can check this standard means Windows.

For this you need:

In order to update the driver you need:

If for some reason installed driver turned out to be not only not working, but also conflicting with other computer software, it needs to be rolled back. Rolling back a driver not only uninstalls but

Important: After any operation to install or reinstall the driver, the computer must be restarted.

To install the driver, you need to perform the following steps:

1. most sound card drivers come with startup files. by clicking on such a file, the installer is launched, following the simple prompts of which you can install the driver and immediately perform its necessary settings;
2. if the driver is supplied without an installer, it can be installed in the same way as updating the driver;

System Restore

If, along with the loss of sound, the computer starts to display system error messages, most likely a system failure has occurred, which can be fixed in two ways:

1. restore the system;
2. reinstall the system.

Important: System Restore in Windows is based on checkpoints that must be created well in advance of problems with the system. If there are no restore points, it will be impossible to restore the system.

In order to restore the system, you must:

It is better not to use the computer during the system recovery process. The system will notify you about the completion of the restoration with a message.

Sound output device not working

There are several ways to check the performance of a sound card:

In the first case you need:

If the window shows that the device is turned off, and the system does not allow it to be turned on, most likely there is a hardware problem with the sound card.

An easier way is to connect USB headphones to the computer. Such a gadget is equipped with an external sound card that works out of the box, so if you hear sound in the headphones on the computer, the built-in sound card is most likely defective. The lack of sound in the USB headphones will indicate that the problem is not hardware.

Sound Management Service Check

For this you need:

• click on the "run" button in the "start" menu. In the window that opens, enter the services.msc command;
• in the services window, select the "window saudio" service;
• if it is displayed that the service is disabled, you need to double-click on it to enable it.

Diagnosing and fixing audio problems varies slightly between operating systems.

WindowsXP

XP does not have a feature to search for programs from the start menu. Therefore, in order to open one or another utility, which is discussed in this article, you need to know its location. For example, the System Restore utility is located at: Control Panel - System - System Restore tab.

Windows 7

"Seven", unlike XP, has a built-in utility for automatically diagnosing and fixing system problems, including with sound. This function starts automatically, but it can also be started manually directly from the window where the problem occurred by clicking on the appropriate button.

Reinstalling modem drivers

Windows 8

This version of the operating system does not have a start menu, which we used to access some system settings. "In the Eight" you can access any utility simply by entering its name in the Metro-search window, which opens when you move the mouse cursor to the lower right corner of the desktop.

Windows 10

AT latest version operating system, the start menu and the metro menu work simultaneously. At the same time, the search box necessary for diagnosing problems with sound has been returned to the start menu. Therefore, the elimination of problems with sound in this operating system is carried out in the same way as in the usual “seven”.

Why is the sound card not working on my computer?

The sound card on the computer may not work in two cases:

• it is faulty;
• it is not properly connected to the computer or its contacts have gone.

To understand whether the sound card is working or not, you need to exclude the waste of contacts. for this you need:

• carefully unscrew the cover of the computer system unit;
• unplug the sound card and insert it back until it clicks.

A sound card is a card with speaker connectors, it connects directly to the motherboard, usually through a PCI connector. To disconnect a poorly fixed sound card, you need to press the latches located on the sides of the slot, and then pull the sound card towards you.

If after the manipulations the sound does not appear, most likely the sound card is out of order and needs to be replaced.

Sound Manager

Any operating room Windows system has a built-in sound manager, the incorrect setting of which may be the reason for its absence. Some sound card drivers come with a proprietary "sound manager" utility.

Sound managers are accessed through the volume control in the taskbar tray and a special branded manager icon next to the volume control. The manager allows you to assign a default audio output device. The wrong choice can sometimes lead to absence.

To check the dispatcher, you need:

Registry

Through the registry of the operating system, you can make the most subtle settings of the system. But changes in the registry can lead to remapping of the sound card sockets, which will lead to no sound.

You can fix this problem by changing the binary parameterpin01, responsible for the rear green jack that should be used for audio output.

For this you need:

Important: If you are not sure what actions you are doing in the registry, it is better not to change anything. Actions with the registry are irreversible.

Jumpers on the motherboard

On some, especially older motherboards, there are jumpers that switch audio output from the front to the back and vice versa. If the jumpers are set incorrectly, there may be no sound.

For sound to appear:

1. unscrew the cover of the system unit;
2. close jumpers 5-6 and 9-10 contacts.

Uninstalled audio codecs

In some cases, the problem with sound is essentially a problem with the playback of audio files of a certain type of codec for which the system does not have. Therefore, it is recommended to check the sound performance with wma or wav files. Codecs for these formats are included in the basic version of any operating system.

To play the sound of other audio formats, you need to download a codec pack, such as K-lite, or install a player that uses its own codecs, such as GOM or VLC.

Front Panel

The reason for the lack of sound on the front panel may be:

• incorrectly set jumpers on the motherboard;
• lack of connection of the front panel to the motherboard.

It is very common for computer builders to build in the front audio jack panels for a model without connecting them to the motherboard. In order to connect the front panel to the motherboard, the pin cables that come with the panel are used.

You need to connect the pins to the front panel of the motherboard, which is usually located in the lower right part of the board.

Rivalry of several drivers

Even if all drivers are installed, they may not work due to conflict with each other.

This problem is solved as follows:

• updating all drivers to the latest version;
• installing only original drivers.

On laptops, a driver set that differs from the factory configuration may conflict. You can find out the basic set of drivers on the official website of the laptop manufacturer in the "support" section.
