Quite often, users are faced with the loss of sound on a computer running Windows 7. There are many reasons for this. Some are pretty basic. And sometimes it takes several days to find a problem. This small overview is devoted to how to find and fix a breakdown.

Non-working speakers

Consider possible options breakdowns:

These measures are elementary, but you shouldn't forget about them either. If the check yielded nothing, then it's time to move on.

Sound hardware settings

After the obvious faults have been checked, it is worth paying attention to software settings sound. It is possible that the sound is muted or muted in Windows. If it is reduced so much that it is barely audible, then the user, with a high degree of probability, will assume that the computer itself has broken.

It is best to see clearly how the sound is configured, using the example of Windows 7, on Windows 8 and 10, the principle of operation is the same:

Let's consider the functions of the opened window in more detail:

If you could not play the test sound, it is worth checking, and not whether the sound is reduced to the minimum value or turned off altogether:

Check device manager

If there is no sound on a computer running Windows 7, as well as operating systems Windows 10 and other versions, you should check the status of the gadgets (drivers) for the sound card. Most likely, they need to be updated or they do not exist at all.

You can check the status of the equipment and drivers for them in " Device manager", Which is easy to find in Control panels on the tab “ System».

System displays all devices that are present on the computer or laptop, as well as the status of the drivers for them. If there is a yellow triangle next to it, you should pay attention to it first. This means that the sound card is not working at all or is not working properly. In our case, we are interested in the item " Sound, video and game devices».

If you find a problem that causes the sound to not work, you need to download and install a driver that is compatible with your PC. The current state of the computer can be maintained using special utilities for automatic updates and search current version drivers for any hardware on a PC or laptop. For example, the program Everest will determine the model of the sound card, check all drivers for relevance and tell you where to find the necessary drivers for sound on Windows 7.

When you monitor the current state of your computer and carry out regular updates, then during the next automatic driver update you may encounter the problem of no sound. An updated driver may be the source of the problem. To restore the working situation will help "". On the tab “ Driver»Of your sound card, you must click the Rollback button.

If the problem goes away, it's best to disable automatic update drivers for this device.

Updating drivers in Windows 10

The algorithm of actions consists of the following steps:

1. If the Internet is connected, then in the browser search engine you need to type a search query like: (Your_Laptop_Model) support or (Your_mother_board_Model) support.
   
2. In the support section, select your computer model and click Select.
   
3. From the Driver-Audio line, select the download to your computer of the entire set of drivers that are in this list.
   
4. If you are prompted to download drivers for Windows 7 or 8, and not for Windows 10, it's okay, at least it's better than nothing. The main thing is that the bitness of the operating system does not differ from the installed one (x64 or x86). The driver that is absent in the system is included in the kit that the official website offers.
   
5. After the drivers are loaded, you need to install the entire kit. If the system requires you to enable legacy compatibility mode Windows versions, it must be done.
   
6. After that, check whether a sound has appeared or not.

No codecs on audio / video

If there is sound in browsers, but there is no sound when starting a video on a PC, then you should look for a problem either in the media player itself, or in audio codecs.

For continuous video viewing, it is recommended to use CMR player... He has already proven himself and shows good results. The creators of the program have provided a lot of all kinds of codecs for video playback. And, as a rule, most films are successfully reproduced in this program.

The problem with codecs can be radically solved with the help of the package K-Lite Codec Pack ... It can fix the missing sound problem. It has a full set of up-to-date codecs that open almost all popular formats, both video and audio files.

Viruses and adware

Sound problems on Windows 7 operating systems may mean that a virus has appeared on the system. There are many types of viruses and they can negatively affect the operating system.

How to behave if the sound on the computer disappears and there is a suspicion of a virus:

• Take a close look at the work of the computer as a whole. If it starts to freeze frequently, to slow down unexpectedly, then, most likely, the PC has undergone a virus attack. If the installed antivirus program failed and missed the virus attack, then it is best to check the system with a third-party antivirus with up-to-date virus databases. For example, you can use the utility Dr.Web CureIt... This curing utility successfully cures an infected system.
• You can try to check your computer with Live CD(emergency boot disk). With its help, you can download a light version of the operating system with a ready-made antivirus. If, when booting the restored system from Live CD sound appeared, then, most likely, a malfunction in Windows 10 itself. Most often, you will have to reinstall it or perform a system restore using restore points, if this mode was enabled and restore points were created.

Checking BIOS settings

If a built-in sound card is installed in a computer or laptop and there is no sound even in the headphones, then you can see BIOS.

This measure is extreme - in the factory settings AC97 is enabled by default. If the settings are lost, then the sound device in operating system Windows will not work.

Each computer logs into BIOS differently. For example, for ACER computers, press and hold the Del key before booting the system. In general, before loading the operating system, it is necessary to indicate how to enter the BIOS.

After pressing the Del key, the following dialog box will open, in which you need to select the item " BIOS Setup».

In the window that opens, you need to find an inscription of the AC 97 Audio type, select this inscription with the arrows on the keyboard and click on the Enter key. A dialog box will appear to select which function to activate HD Audio or AC97. We are interested in the inscription AC97 "Auto". Confirm your choice and exit this section with the ESC key. We exit the BIOS, saving the settings.

If it was not possible to return the sound after changing the BIOS settings, then the last way out is to replace or send for repair sound card.

The problem when there is no sound in the Windows system is often faced by laptop owners. Frequent overheating of the sound chipset causes the computer to malfunction. And the rest of the electronic filling simply suffocates from dust, unless, of course, you do regular cleaning, and gradually breaks down, which can also lead to loss of sound on the laptop.

Conclusion

Of course, these are far from all the reasons why the sound may be absent, but the main, most common versions are revealed.

So, we told you how to restore sound in Windows 10, 7 and 8. And our main advice is not to despair, but to try all the options step by step.

The most common reason for no sound is to mute it or set the volume to minimum. If your computer is not playing audio, hover over the speaker icon in the tray (at the far right of the taskbar). The tooltip will indicate the current volume value. If the sound is not played in a separate application, check its settings. If enabled in the settings, audio playback in a specific program may be limited in the mixer. To test, right-click on the speaker icon and select "Open Volume Mixer". There you can turn on the sound and adjust the volume level for each program running on your computer.

Check the volume on the playback devices themselves: headphones or speakers. When using speakers, also make sure they are connected to power and the power button is in the active position. Checking your speakers or headphones is pretty easy. To do this, it is enough to connect any other device instead of a computer to the audio output: a smartphone, a player.

Important! Also check your speaker settings. To do this, go to "Playback Devices", and in context menu speakers or headphones, click "Properties".

Incorrect operation of audio drivers

Another common reason why your computer may not have sound is missing or damaged audio drivers. Hover over the audio icon in the tray to identify this problem. If you see “No Audio Output Device Installed”, the audio drivers are causing the problem.

To eliminate these difficulties, right-click on the same icon and select "Detect problems with sound" from the context menu.

This will open a troubleshooting window. Wait while the sound diagnostics run on your computer. Depending on the speed of the device, the process can take from a few seconds to a couple of minutes. If the determination of the cause of the malfunction stops in one place, click "Cancel".

When the audio diagnostics are complete, the system will prompt you to choose which device you want to troubleshoot. In this case, the device used should be noted based not on its type, but on the location of the audio input. For example, if your speakers are connected through the audio input on the front of the computer, check the second box, even though headphones are listed there.

If there is a hardware failure, the diagnostic result will be the following window. It may indicate damage to speakers or headphones, but the most common cause of difficulty in audio devices is broken or damaged connecting cables.

At the last step of the sound diagnostics, the result of its execution will be displayed. If the issues are resolved, close the troubleshooter. If the diagnostics did not help, click "View additional features". You can also find help information about the causes of the malfunction by clicking on the link "View more information".

Incorrect connection or installation of the device

Sound may not work due to improper connection or installation of sound devices. To resolve this issue, check if the correct input is selected to connect the device to the computer. Speakers or headphones may be connected to the microphone input and will not work.

Go to "Control Panel -> Device Manager" and check the status in the "Sound, game and video devices" menu. If a yellow mark with an exclamation mark is displayed next to the name, the cause of the problem is an incorrect installation or malfunction of the device.

Note! If the audio hardware does not appear in the manager at all, update the configuration from the Actions menu.

Right-click on the audio hardware and select Properties, then go to the Driver tab in the window that opens. To update the configuration, click the Update button. Here you can uninstall the driver for its subsequent reinstallation.

In the next step, choose where you want to search for sound drivers. Two options are offered: an automatic search, which includes a search on your computer and the Internet, and a simple search for drivers. We recommend that you select the first option to detect drivers.

Important! If the sound card is outdated and its driver is on separate disk, first copy it to your computer.

The scan will take about 20-30 seconds, after which a message will be displayed in the search window about the successful installation of the new audio drivers. If the device already has the latest available driver installed, the configuration will not be updated.

If the driver update did not bring the desired result and the device still does not work, it is recommended to remove it from the system. To do this, right-click on the name and select "Delete". Confirm the deletion in the dialog box by clicking "OK".

After that, in the "Action" menu, you need to update the list of equipment. A search will be performed for devices connected to the computer. If the desired device does not appear after searching, restart the manager.

When the speakers are found, installation starts automatically. This process can take several minutes. When finished, a message will appear stating that the speakers are successfully connected and ready to use.

Damaged connecting cables

Standard 3.5 mm connectors may fail as a result of mechanical damage. Usually breakage occurs at the base of the connector - at the point where it connects to the audio cable. The break can also be on the cord itself. The most common cause of damage is pinching by furniture (table legs, chair wheels). Pets can also chew on the cable. You can diagnose a breakdown visually or by connecting another cable to the speakers.

Physical breakdown of audio equipment

Even if the speakers or headphones you are using fail, you may not hear sound from your computer. It is not difficult to determine this - it is enough to connect another audio device to the same audio input. If it works, the reason is the broken speakers, not the computer settings.

Disabled Windows Audio Service

Another common reason for no sound is the disabling of the Windows Audio service. This background process is responsible for processing sound data and is always running on a running computer by default. However, when making changes in the system parameters, incorrect Windows Audio settings may be indicated. Also, the service can be disabled by malware.

Hello everyone! Modern computer user (unless of course you are an office worker) it's hard to imagine without music. The lack of sound on the computer is rather sad, because even this note I am writing with a calm track in the background (otherwise blog posts would be dull and uninteresting)... So, I want to tell you about my experience and answer the question - why is there no sound on the computer?

With the move to Windows 10 and the arrival of HDMI (where video and sound goes over the same cable and your video card has an audio chip) problems have become even more ... this is especially true if your computer is not the first freshness, although it coped well with the tasks on Windows 7.

The first thing to do if there is no sound on the computer is to check the cables and make sure that the speakers (or headphones) included. Quite often, a banal reconnection of speakers helps - if you have already tried all this and the problem behind the sound has not been solved, then you can start reading the note.

Check your driver and your sound card

If you connected the speakers to the computer, but there is no sound ... then you have to go to the device manager and see if everything is fine with the hardware and whether we have installed sound drivers. Getting into Device Manager isn't difficult - open the Start menu, type Device Manager and press the Enter key on your keyboard.

Device Manager will open. Expand the Sound, Game and Video Devices tab. Find in the list (if there are several) your audio device and double-click on it to open its properties. Check the system message, the driver must be installed and the device is working properly.

Try to update the driver - this is done in the "Driver" tab. A simple reinstallation of the device often helps ... to do this, right-click on your audio device and click uninstall (but do not remove the driver itself - the system will ask you about it)... After that, click the "Update hardware configuration" button at the top. This way you reinstall existing driver devices.

Don't be surprised if you find you have multiple audio devices - this is normal. Almost all modern computers or laptops have an HDMI video output that can transmit sound and video over one cable

Choosing the correct default audio device

Open Control Panel and open the Hardware and Sound category. Select "Sound". (why can't I click on the icon next to the clock? - It's simple, in Windows 10 Spring Creator Updates the interface has changed slightly and I will describe it below)

Here we are interested in the "Playback" tab and the list of devices. Let's take an example - I have a laptop connected to an external monitor via HDMI. The monitor has its own built-in speakers ... so you just need to tell Windows which device to use for audio playback.

In the example below, as indicated by the green flag, we see that the sound is played through the monitor (except that the speakers on the monitor are reduced to zero! Therefore, there is no sound on the computer)... You just need to select standard speakers and sound problems will disappear

It is possible that after choosing a different default audio device, you need to restart the programs, or better in general, restart your computer for the new settings to take effect.

In Windows 10 v1803 continue to nag Windows decoration 10 in a new style and in new version affected these changes to the sound parameters. In general, there is nothing complicated - right-click on the "Speakers" icon next to the clock and select "Open sound options"

Everything is the same here, just select the output (playback) device from the list and enjoy the sound on the computer.

Several audio devices will be active if you connected the TV to a laptop or computer via HDMI ... you may be using Bluetooth speakers and many many others…

Disable sound enhancements

In the control panel (in the same place where the default sound devices were selected on the "Playback" tab) right click on "Default Playback Device" and open its "Properties". On the Enhancements tab, select Disable All Sound Enhancements and check if the sound is working.

If these manipulations helped - this is good news, disable sound effects for all your audio devices.

Check speaker or headphone connections

Almost all modern computers are equipped with at least three connectors, which must include:

1. Microphone jack
2. Line-in
3. Linear output

(the exceptions are laptops, quite often they are combined and have only one dual-purpose connector - a microphone and a line-out)... Make sure your speakers are connected to line out (it is usually colored green).

Maybe the advice is so-so, but you can try connecting to all connectors in order to determine the one you need by typing

I would like to draw your attention to the fact that when you connect headphones on the front panel of the case system unit the speakers will turn off - do not forget this nuance.

Misunderstandings with sound or dealing with HDMI

This problem certainly deserves a separate note, but I will try to tell it in the context of our problem. If you connected a TV via HDMI and are faced with the lack of sound on it, you need to delve a little into history.

If your computer and TV are completely new, then most likely you have chosen the wrong default playback device, you can read above how to change it.

If your computer is no longer young, then it is quite possible that although there is an HDMI connector on your video card, it cannot transmit sound through this cable. In this case, either change the video card, or connect the sound to the TV with a separate cable (if possible).

In the control panel, open the properties of your default playback device and go to the "Advanced" tab. In the "Default Format" section, check each of the available ones in turn.

If it helps, save the settings and enjoy the sound on your computer. However, as practice has shown, this way helps very rarely.

If you are already desperate and have tried all possible options, then starting with Windows 8 there is an opportunity to automatically try to fix the problem with no sound on the computer. Click on the speaker image in the taskbar and select "Troubleshoot sound problems"

Next, you need to select your playback device and follow the prompts ... if you look closely at the points, you can see that the system itself tries all the above methods and, if possible, combines them. Surprisingly, this method often helps, especially in cases where you have chosen the wrong device for sound output in the system.

Outcomes

Well friends, in this guide I described the most common problems with no sound on the computer. In fact, there are many more reasons why there is no sound on a computer or laptop, but it is better to consider them privately. If these methods did not help you in any way, then please describe your problem in as much detail as possible in the comments - I will definitely answer and try to help you.

What to do if sound disappears in Windows XP?

Imagine a situation: you turn on the computer, and instead of hearing a sound Windows greetings XP, only the uniform hum of the system unit is heard. Of course, the problem immediately becomes clear: there is no sound on the computer! What can you do if this situation arises? Are there any special methods of action that are aimed at restoring sound? Let's see what you can do in a situation where the sound on your computer has disappeared.

Reasons for no sound

There are only two reasons for the lack of sound on the computer: it is either a software problem or a hardware problem. In other words, either there are faulty components or there are various problems in Windows settings XP or specific software... It should be noted that such problems can occur both in the latest operating systems and in the usual Windows XP (problems with sound occur quite often due to a malfunction of the svhosts.exe file). And even in spite of the latest equipment, a powerful and high-quality sound card, problems have and will continue to arise.

We will not consider the situation in which the sound disappeared due to a hardware malfunction. Problems can be very diverse and a user without special skills and education is unlikely to be able to figure out the reasons for the lack of sound due to a malfunction motherboard, sound card, or other hardware on your computer. If all of the following steps do not lead to a positive result, then the problem is not at all in Windows XP. The problem lies in the hardware of the computer. It is advisable to refer all the equipment for diagnostics to a person who can figure out why the sound on the computer disappeared. We will consider the most common malfunctions that occur with the software.

No sound due to software

If the sound is missing, then first of all you need to check if the Windows Audio service is running:

• Go to the address Start-Settings-Control Panel-Administrative Tools-Device Manager-Services;

• In the dialog box Services you must select the Windows Audio service;
• Select a subsection of the menu Action-Properties;
• The Windows Audio dialog box checks the status of this service. During normal operation, it should function correctly, while the button Start is inactive;
• In the context menu Launch type should be Auto(if this is not the case, then you must set this value);
• The last step is to click the button OK and closing the window of the special service.

After the steps taken, you need to check the operation of Windows XP audio devices. To do this, follow these steps:

• IN Control panels you need to select a section Sounds and audio devices;
• Most likely, when you open this section, the message “No audio devices” will appear;

• Moreover, in Device manager In chapter Sound devices you can see the following picture:

In order for the sound to appear again in Windows XP, you need to install new drivers... This is done as follows:

1. In the CD drive, you need to install the CD that contains the motherboard drivers.
2. Do not use autorun. You must cancel the unattended installation and open the contents of the CD through My Computer.
3. Among the contents of the disk, you need to find the installation file Setup.exe (Install.exe). After starting the file, the Found New Hardware Wizard will open, which will install the drivers on Windows XP.
4. The last step is to reboot the computer, which is necessary for the drivers to work correctly.

After reboot, you can open the tab Volume and adjust the sound in the way the user needs.

There are several important nuances to consider. First, there is a special Windows Audio service for all audio devices in Windows XP. In the event that this sound disappeared on the computer, then this may mean the inactivity of this service. Secondly, the above malfunction with Windows service Audio most often occurs during installation or reinstalling Windows XP. This situation arises due to automatic installation driver on the motherboard, so it is recommended to install them manually via Device Manager.

How do I restore sound on my computer?

If the sound disappeared on the computer, and reinstalling the motherboard drivers did not bring any visible result, you can follow these steps, which, despite their banality, can be very useful:

1. Initially, it is recommended to restart your computer. It is possible that there was a temporary system failure of the drivers, and upon repeated Windows startup XP sound will reappear.
2. The most common reason that at least once caused panic even among an experienced user is the lack of a speaker power connection. It's trite, but it happens. Therefore, it is worth checking whether the plug from the speakers is inserted into the outlet and whether the outlet is working properly.
3. On the Windows XP taskbar, you need to find the icon Volume setting and then move the slider up as far as possible.
4. It is recommended to check the functionality of the speakers. If the sound is lost due to the computer, then the speakers will work on other devices. If the speakers do not work in all cases, then the reason for the lack of sound lies in them.
5. Install sound card drivers. Even if there are no drivers available, they can be found on the official website of the company that owns the sound device on your computer.
6. If you understand more than just the operating room Windows system XP, but also in hardware, you can try to put a known working sound card on your computer. If at the same time the sound appears, then it is necessary to refer the sound card to the diagnostics. It is possible that the sound was lost precisely because of her.
7. As a last resort, you can try automatic recovery systems. To do this, you need to create a restore point on your computer so that all settings are in working order. In the future, this may come in handy if in Windows XP there will be any problems with the operation of software or individual components.

If the sound disappeared and all the above actions did not bring any visible results, then only an experienced specialist can deal with this problem.
