The sound does not work well on a Windows 7 computer. Why is there no sound on the computer? Sound restoration

This article was written specifically to help users solve any problems related to sound. After all, if there is no sound on the computer, then there can be quite a lot of options for the problem, and searching throughout the network for your specific case is very time-consuming and inconvenient. In addition, the Internet is filled with articles that are outdated in their content, which discuss how to fix it in the operating systems Windows XP, Vista, or at best Windows case 7. Now I will tell you what to do if the sound does not work in Windows 10. There are several reasons why there is no sound in the system, and we will look at them all.

7 possible reasons why there is no sound on the computer

The most common case, which is mostly solved in half a minute. It's no secret that for the device to work, it needs to be connected correctly. If the speakers or headphones do not work, check where the wire responsible for the sound is inserted. Typically, the system unit has two or three outputs responsible for sound. They are called linear and look like this:

The output we need is green. Typically one is placed in front system unit, specifically for connecting headphones, and the other at the back. If you see several sound outputs, try to check everything. It’s just that one of them is connected to the motherboard, and the other belongs to the sound card. Insert headphones into all outputs one by one and listen for sound.

From the speakers there is a cable, at the end of which there is a plug, usually framed with green plastic or rubber. It is this that needs to be inserted into the linear output, also marked in green. And yes, check if the speakers are plugged in and if the power indicator on them is on. Sometimes something as small as unplugged speakers can make people think their computer is irreparably broken.

Advice: “Always carefully read the instructions for the equipment, this will help to avoid many problems.”

Reason #2: The sound is simply turned off

A common situation is when you accidentally turn off the sound on your computer while doing some work. To turn it on, you need to resort to the volume control located in the lower right corner of the monitor, which is a drawn loudspeaker. Rice. 0. You need to click on it with the mouse. If you see a picture like this,

then the MUTE key was used (complete instantaneous shutdown).

Or do you see something like this:

here the sound is reduced to a minimum and also does not work. Using the mouse, turn on the sound and set it to the desired level. If the volume control is fine, something may be wrong in the speaker settings. Click the Start button in the lower left corner, then find Settings.

Here are all the settings of our computer, including sound. Type “Sound” in the text field and in the drop-down list you will see the full sound settings computer. Press Enter.

Find “Manage audio devices” in the list and left-click.

A window with audio device settings will open.

Make sure that your device is in the list and that it has green tick. This means that it is running and functioning properly. Next, go to its properties.

Take a close look at all volume controls. They should be set to maximum and there should be no crosses anywhere, like in the picture.

Advice: “If you don’t know what will happen when you click on an icon, then it’s better not to click.”

Reason #3: Sound card is damaged

This is a more complicated case, but also quite solvable. First, you need to determine what exactly is broken sound card. Moreover, now we are considering physical damage, not software. That is, the card burned out or failed.

Open the system unit and visually determine where the sound card. It is usually inserted closer to the bottom motherboard and is secured with a latch. At the back it has a line output where speakers are connected. Carefully remove the card and clean it from dust if necessary. Look carefully to see if there are any swollen parts or visible damage on the surface.

Try inserting a different sound card (you can borrow one from a friend) or connect the sound cable to the line-out port of the motherboard.

If the sound appears, you will have to buy new map replace the burnt one, or use the built-in sound card. Remember that sometimes simple cleaning can restore the device.

Advice: “Always keep the inside of the system unit clean and it will work much faster.”

Reason No. 4: drivers are not installed (damaged)

In order for anything to work computer device, he needs a special program. It's called "driver". Whether it's a mouse, keyboard, or anything else, they all need to have the correct drivers or they simply won't function. Let's check if you have installed required driver to the sound card. Go to Settings, then type Device Manager in the search bar.

Click on it. We are interested in the item “Sound, gaming and video devices”. It contains everything that is installed on your system.

As you can see, opposite the two devices there is a black arrow in a circle. This means that in at the moment the device is not used. And if there is a yellow triangle or the inscription “ Unknown device", which means you need to install the driver.

Right-click on it and click Properties. A window with device properties will open. This is where you can update, remove or roll back the driver.

First, click on “Enable”, this will turn on the device if it is currently disabled.

If there is no driver (the yellow triangle is lit in the “device manager”), click “Update”. Turns on automatic update driver, you just need to choose where to look for the driver, on your computer or on the Internet.

"Roll back driver" returns previous version, if suddenly any problems arise during installation.

“Delete” is the last resort. Happening complete removal devices from the system. Then you need to restart the computer and, perhaps, this time the system will correctly detect the sound card and automatically install the necessary driver. In this case, you must be connected to the Internet, since Windows 10 uses its driver database, downloading them from the network. Then you need to check the sound, most likely everything will work.

Advice: “If your sound card came with a disc, install everything you need for the device from it. This the best way make the device work correctly."

Reason No. 5: The Windows Audio service is disabled on the computer

Everything that happens on your computer is controlled by Windows services. Sometimes, due to certain software faults, these services begin to work incorrectly, which leads to errors, and in our case, to the fact that there is no sound.

To check that the service we need is running, go to Settings, type Services in the text box, and then click View Local Services.

In the window that opens, find the required service " Windows Audio».

The word “Running” must be present next to it, otherwise the service is disabled. Using the right mouse button, call up the context menu and select the “Run” sub-item in it.

Advice: “Don’t mess around with system settings, this can lead to irreparable consequences.”

Reason No. 6: a computer virus is to blame or programs are conflicting

If the sound suddenly disappeared when you were not doing anything, or after restarting the computer, then there is a high probability of infection with a virus. Most of them do not affect audio devices, but some create problems that completely block sound from the system. Many antivirus programs do not always find such viruses, and if they do, they remove them so that the sound still does not appear.

To solve this case, I recommend that you install the EMSISOFT Anti-Malware program. Being, in fact, a utility, it does not conflict with any antivirus and instantly removes malicious objects. You can download it from our website; in addition, there is a free 30-day version of the product. After installation, click “scan for threats” and the program will find all viruses in the system and restore its functionality.

If the sound disappears after installation specific program, just remove it and reboot the system. Typically this should help.

Reason #7: Audio codecs are not installed

It also happens that system sounds are reproduced, and when music and movies are started, there is complete silence in the speakers. How in in this case restore sound on PC and fix the problem? Since there are a huge variety of sound formats, there is a special thing so that they all work and run on one computer. It's called a "codec". For example:

WMA and so on.

Each of them is needed to launch and correct operation one of the audio formats.

In order not to go through and install them all, there are special assemblies that include most of the well-known codecs. The most famous assembly is called and it consists of a huge archive of sound codecs that allow you to play any known audio formats.

After installation, everything will turn on automatically and problems with no sound are guaranteed to be corrected.

Tip: “Always keep your codec database up to date.”

That's all. I hope the article was useful to you and the question of how to connect sound on a computer is no longer a problem for you.

It's hard to imagine a funnier situation than watching the next Comedy club episode on a PC without sound. However, this kind of computer malfunction is far from uncommon in user practice. Big to that An example is the irrepressible popularity of questions about how to turn on sound on a computer. Yes, the “unauthorized boycott” declared by your PC is definitely unpleasant surprise for many novice users. Especially when you consider that the problem with sound is very multifaceted in resolution. However, you, dear reader, are in luck again! Since in just a few minutes you will be able to “untie the tongue” of almost any operating room Windows 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 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 firmly sure what type of sound problem you have: hardware or software. However, let's not talk about the bad - everything should be resolved without the intervention of a specialist.

Step No. 1. Basic check

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

First of all, you need to check:

Are the speakers connected to the PC and does the jack used correspond to the destination device?
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 precisely such “platitudes” that push a person to take wrong actions. Therefore, be careful. Connect known-good speakers. Perhaps all your fears are in vain!

Step No. 2. Detect “secret” signs

If there is no sound on your computer, pay attention to the speaker icon located in the system tray. It may be crossed out, which means the playback device is deactivated. Move the slider up. If everything remains unchanged, move on to the next solution point.

Step #3. Windows services

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

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

In order for sound to be played and audio settings to be correctly recognized by the system, you must make sure that the service is active. That is, in the “Status” column the “Running” parameter is indicated, and in the “Startup Type” column the value is set to “Automatic”. Contribute necessary changes You can use the same right mouse button, placing the cursor on the item that requires appropriate editing.

Step No. 4. Driver that may crash

A crossed out speaker in the tray may also indicate the incapacity of the special audio chip manager program code. In other words, the sound on the computer disappears when the driver becomes inoperative.

Open the Start menu.
Then go to the “System” section.
On the left side of the window, select “Device Manager”.

It will not be difficult for you to discover the “culprit” of a problematic situation. In the list presented, a non-working device will be marked with an exclamation or prohibition mark. Update the sound driver using the service disk (software for the motherboard included in the kit). If you don’t have one, you need to go to the manufacturer’s official website and in the “Support” section download the corresponding modification of your PC software tool. It is worth noting that before installing the latest version sound driver, you need to remove the old device management component.

Standard Windows functionality

When all your attempts practical actions answering the question of how to turn on sound on a computer did not bring a fruitful result, it makes sense to use the incredibly convenient “Fault Diagnostics” option. However, this functionality is only available in later versions operating system Windows. To run this fix tool conflict situations, you need to right-click on the conflicting device (indicated by the system with a special warning sign) and select “Diagnostics and correction” in the context menu. In a few minutes, the OS will notify you about the result of the work performed. It is likely that such a sound setting on a computer will become an effective salvation for a seemingly “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 status “Working normally”, then the solution to the question “how to turn on sound on the computer” should be sought using 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. From the context menu, select “Properties”.
While on the “General” tab, pay attention to the “Device Usage” item below. More precisely, the value in the checkbox. Apply the On option.

In the case when the mentioned list contains several installed devices playback, one of them should be set to “Default”.

Step #6: Audio Controller

As a rule, most manufactured motherboards implement advanced sound scheme. That is, the integrated audio chip can be controlled through a special installed driver. Let's look at an example where setting up sound on a computer is done using Realtek dispatcher HD.

Click on the speaker icon (darker in color and slightly large sizes than the standard Windows volume control).
In the dispatcher working window that opens, you need to activate the icon in the form of a wrench (bottom part of the interface, on the right).
In the case when no sound is played, it is necessary to change the diagram from one value to another (meaning “Front panel of AC"97” and the item of the same name located just below).

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

Step No. 7. Unclear media format

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

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

Usually this action gives the PC “omnivorous” multimedia capabilities. Rest assured: your computer will not be an exception to the rule.

Step No. 8. Software incidents

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

Step No. 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 may turn out to be an impossible mission when the audio functionality is disabled for some unknown reason in the BIOS. However, knowing the main rule when working with basic system: “Do not touch or change unknown values”, you will successfully complete the task.

To check whether the audio function is enabled in the BIOS, you need to do the following:

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

Step #10: System Restore

If, after all the manipulations, the question of how to install sound on your 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.
Once the section you are looking for is displayed at the top of the service window, press Enter.
Select the required backup copy and confirm your choice with the appropriate key.

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

Step #11: Damaged or Missing OS Files

Sometimes the question of how to make sound on a computer is solved by restoring lost recordings in 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 drive) deletes important OS data. Ultimately, the inevitable happens - Windows loses full functionality. However, the unfortunate user does not always have the opportunity to roll back the system to original condition. By the way, the fault is still the same known cause- saving space on the HDD, that is backup copies There is simply no 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, enter cmd.exe
· In the command window, type sfc /scannow.
Press Enter.

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

Step No. 12. Viral infection

Malicious code not only steals and destroys user data. A virus program that has infiltrated the operating system environment may also be the reason why the sound on the computer is lost. In order to identify a pest, it is necessary special software. Often traditionally used for protection antivirus program not quite enough. However, today there are plenty of effective malicious code destroyers on the Internet. Therefore, you should not have any particular difficulties in the process of finding the necessary software tool.

To ensure that your PC never experiences sound problems, periodically check on the official website of your manufacturer (motherboard manufacturer) to see if more latest versions drivers.
When connecting audio playback devices to the PC system connectors, it would be a good idea to understand in more detail the correctness of the connection diagram involved.
Often motherboards have special contact pads that can be connected with special jumpers in order to reassign the audio output. Therefore, it is worth turning to the documentation of the motherboard and studying the problematic issue in more detail.
If all methods fail to meet 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 large question. However, today you have learned a lot of information about what you need to do to “talk” your electronic friend, and what you should be wary of while using it. All the best to you and pleasant sound experiences!

Follow the steps listed in order. The first one doesn’t help - move on to the second one and so on.

If the sound is gone on a Windows computer

1. If there is no sound only in headphones or external speakers, make sure they are properly connected to the computer and power source. If your audio device has a switch or volume control, check it.

2. If there is no sound from the built-in speakers, make sure that headphones and other audio devices are disconnected from the computer ports.

3. Check the status of the audio device. To do this, right-click on the volume icon and select “Playback Devices”. Make sure required device enabled and used by default. If it is not, change its status using the surrounding buttons. If you see a list of several devices and don’t know which one to choose, turn them on one by one and check the sound.

4. Check the audio levels in the system mixer. Right-click on the volume icon and select “Open Volume Mixer.” Move the sliders and check for sound.

5. Restart your computer. This will help if the sound is lost due to a simple software glitch.

6. Check the Windows Audio service. To do this, open the “Run” window (Windows + R), enter in the field services.msc and press Enter. In the list that appears, find Windows service Audio and open its properties double click. Make sure its startup type is set to automatic. If this is not the case, change the value to “Automatic”, click OK and restart your computer.

7. Reinstall the sound card driver. It can be downloaded from the disk that is sold complete with motherboard, or on the manufacturer's website. If you don’t want to search and install the driver manually, you can use it, which will do everything for you.

8. Install the latest available updates for your Windows versions. This can be done in the Center Windows updates", which can be easily found by searching the system for the query "updates". If it doesn't help, try it.

9. If none of these methods work, you can take the computer to a service center.

If the sound is missing on a computer with macOS

1. If only your headphones or external speakers have no sound, make sure they are properly connected to your Mac and power source. If your audio device has a switch or volume control, check it.

If possible, connect headphones or speakers to another computer and test them. If they don’t work, you can take the accessory to a service center.

2. If there's no sound from the built-in speakers, make sure your headphones and other audio devices are disconnected from your Mac's ports.

3. Turn off your computer and unplug the power cord for 30 seconds, then plug it back in. After 5-10 seconds, start your Mac again and check the sound.

4. Check your audio settings. To do this, open apple menu and go to the section " System Settings» → “Sound”. Under the Output tab, select the type of audio device (built-in speakers, audio monitor, external speakers, or other) that is not producing audio. Make sure the "Mute" checkbox is not checked, move the volume slider and check for sound.

5. Update macOS to the latest available version. To check for updates, open App program Store and on top panel tools, click on the “Updates” button.

6. If all else fails, contact service Apple support or to the service center.

Let us immediately note that there can be many reasons for this problem, therefore, there will be many solutions. In this regard, it is worth warning that in order to follow the recommendations, it is worth setting aside separate time to work on your computer or laptop. If you try to do everything in a hurry, nothing good will come of it.

So, how will we work with you? To make the task easier, we will divide the problem into categories:

To make your work easier, you can immediately select your connection type and go to the appropriate block. There will be two of them, which will completely answer the question of why there is no sound on the computer:

Speakers, headphones and others external sources sound. Both wired and wireless types are considered here.
The software part, which deals with solving problems with drivers. Those who have built-in speakers (for example, on a laptop) also go straight to this block.

Please note that after each step a playback check is required. To do this, it is advisable to use the same file: it can be a video on the Internet, so that there are no problems with the file itself on the computer. For example, you turn on a song and there is no sound, but it turns out that the file is damaged. What to do if there is no sound on the computer? When you are completely ready to find out the answer, move on.

Speakers, headphones and other external sound sources

So, the sound on our computer does not work. How to enable it? First, you should check the correct connection of the wires that provide connection to your devices. That is, if you insert the cord into the wrong socket, then, of course, there will be no sound on the computer. To do this, you can refer to the speaker instructions from the manufacturer. If you don't have it, you can find it on the Internet.

Checking that the wire is connected correctly

For wireless devices sound playback you will need to check activity Bluetooth module. It is adjusted by a switch on the speaker body. We check activity in the same way wireless modules on a computer or laptop. If the connection is established through a separate module that connects to the USB of your PC, then try placing it in a different slot.
If the connection is fine, but there is no sound, then make sure that you turn on your speakers using a special button or switch, which is most often used in systems with a subwoofer. Some models are equipped with an indicator light, mainly having green when turned on.
Next, we will check the sound volume on the speakers: turn the volume button (where Volume is written) towards increase. If you have no problems with this, but do have problems with playback, then move on.

Adjusting the volume on the speakers

If you have additional cable to connect speakers to your computer, then try using it. You can also ask one of your acquaintances or friends. As a last resort, you can purchase it in a store (but it is advisable to do this, only if you are sure that the problem lies in the wire, since this will lead to additional costs).
Try connecting the speakers to another device. You can even connect it to a smartphone or tablet. If the device works on them, then the problem lies in the software part of your computer or laptop. Otherwise, you will need to repair your speakers or headphones. Before this, it is still recommended to buy a new wire, as described in the fourth paragraph above, or immediately take the device to a specialist for diagnostics.
If everything is fine with the speakers or headphones, but there is still no sound, then it’s time to check the software part.

Software part

So, how to turn on the sound if there is no problem with the speakers or headphones? First, make sure that the volume in the settings is set to maximum level. On the taskbar (where the Start button is located in the Windows operating system) on the right, almost at the end, there is a sound logo. Click on it with the left mouse button and move the slider to its extreme value in the direction of increase. For example, if you have a ten installed, then the value should be set to 100 percent.

Move the volume slider to 100%

Now go to the device manager (control panel menu). To do this, write “Device Manager” in the search bar and left-click on the found file. Open the tab " Sound devices"and update the drivers of all audio devices. To do this, right-click on each one and click “Update Driver”. Here, check that the device is not disabled: if the same mini-window says “Disable”, then everything is fine. Otherwise, the device will need to be activated by clicking the item of the same name or the “Enable” item.
If this does not help, then go to the control panel, then open the “System and Security” menu, then click on the “Fix” tab typical problems computer", which is located at the very top practically. In the window that opens, click on “Troubleshoot audio playback problems.” Follow the on-screen prompts to try to resolve the issues.
Often, drivers are not updated, as described in the second paragraph. You can try downloading them on the official website of the manufacturer of your computer or laptop. You will need to enter or find your exact model number, then select the operating system version and only then download the audio drivers.

Why does the sound disappear on my computer? There are many reasons and many solutions to this problem. Most often it disappears in two situations - when you reinstall the operating system or on its own. In any of these cases, everything can be fixed with fairly simple steps.

First of all, you should check the setup of your audio equipment

Therefore, let's find out what to do if there is no sound on the computer, and how to get the audio system working again in Windows yourself.

No sound after system replacement

In such a situation, the reason that there is no sound is usually the drivers - even if the computer displays a message about installed system audio, they may still not be suitable for current version BY.

There is another situation in which the sound disappears, but not due to reinstallation, but after a partial update of Windows - try completely removing the audio system from the device manager and reinstalling it.

Sudden loss of sound

What should I do - the Windows audio service is not running or there is no sound just now, but there was sound before?

You should do the following:

Other ways to restore sound

There is no sound on the computer - what to do and how to fix it? If after replacing drivers or checking the operation of services there is no result, you will have to play with the registry - that is, do system backup to the previous operating state.

This will help us Windows program sfc.exe, after installing which you need to do the following:

Run command line and enter sfc /scannow in the line.
Press Enter, after which the program will check the system files and, if necessary, restore old versions to make the sound work.

The last thing I can recommend is to run Windows check for the presence of viruses - malware can change a lot in the system, including eliminating all sound.

If there are still no results, then the sound card is most likely faulty. What to do in this case? Contact specialists for help or buy another card and simply put it on the computer instead of the non-working part. These devices themselves are inexpensive - unless, of course, you use complex professional equipment.

The same can be recommended when there is no sound quite often, and each time you have to do certain manipulations to restore it. Therefore, it is certainly advisable to try all the above methods to fix the problem, but if they do not help, replace the part with a newer and more reliable card.
