There is no sound on a Windows 7 laptop. How to restore sound on a laptop

You can use the speaker volume control. Almost everyone has one, which is located on your sidebar. If the control was fixed at the value “0” or “1”, then scrolling the control will increase the system volume. As a rule, this is the main reason for sound loss.

The second way to turn on sound on a laptop is to change the mixer settings. In the lower right corner of the screen, next to the clock, there is a speaker icon. When you double click on this icon, your sound card's mixer will appear in front of you. The main system can be set to “0” or completely turned off. Adding the value of this parameter will produce a sound.

Another way to check the sound on your laptop is to control the sound using your machine's hotkeys. Each laptop has its own, which are responsible for the correct operation of certain components, including sound. To turn on the sound, use the Fn key + speaker icon. Most likely, 2 speaker icons will be displayed: pressing one button will increase the volume, and pressing the other will decrease the volume.

If the methods described above do not work, check the connection of the speakers to the audio input jack and the network. Also check the wire connections between the speakers. After connecting all the wires that were disconnected, you will hear sound from the speakers.

If you have lost sound on your computer, then this is of course very bad; you need to figure out why this happened as soon as possible and quickly solve this problem.

The reasons for the sudden lack of sound can be very different, it can be anything at all, so we will look at the 10 most popular reasons. They are suitable for almost any Windows, from xp to 10, including windows 7 and 8.

I will immediately ask you, please take your time before writing in the comments saying what to do, I have no sound on the computer, nothing helps at all. First, consider and work through all 10 steps, I am 99 percent sure that the devil lies in one of the reasons listed.

What to do if there is no sound

Let's start, as usual, with the simpler ones, and end with the more complex ones.

1. Volume controls

Notice the volume icon in the notification area and click on it.

Naturally, the volume slider should be at least in the middle. Make sure it's not at the very bottom.

Well, if the volume icon has a prohibitory icon like this, it means that the sound in the system is completely muted.

Click on it and the sound will appear again.

Here we should also have everything inclusive.

If suddenly one of the sliders is at the very bottom, then move it at least to the middle and then the sound from the speakers will appear.

Don't forget to check the sound on the speakers, make sure that there are no headphones inserted into them; if they are, then you need to take them out.

And so we continue to look for the answer to the question, Why did the sound disappear on the computer?

You need to go into those devices that are different and check.

Click the volume icon and go to .

In the program that opens, find your speakers in the list of devices and check that there is a green checkmark there.

If God forbid it is not there, then you need to right-click on the device and select Use as default.

If your speakers are highlighted in gray and the status is Disabled, then it's easy to fix. Right-click and select turn on, of course Don't forget to make them default.

It also happens that our speakers are not here at all, they are not displayed, in this case you need to click on an empty space and select Show disabled devices. The speakers will then be displayed and they can be turned on as I wrote above, and then set to default.

3. Check your sound card

You need to be sure that the sound card is turned on; if there is still no sound in the speakers, then this point also needs to be checked.

Perhaps it has already been turned on, or maybe it is not here at all, there are different cases if your sound card is not displayed, but there is a section for other devices, for example, audio devices on the bus, and next to it there is a yellow exclamation mark.

This means that the driver has crashed and needs to be reinstalled. I will talk about this in the next paragraph.

4. Check the drivers for sound (Important!)

If you suddenly determine that the sound on your computer has disappeared due to the lack of a driver, then you naturally need to reinstall it.

But for those who have this driver, I still advise you to install it, since most likely the previous version is already outdated and it will be updated with a more recent one.

1. First, let's decide which driver we need to download.
2. Let's go back to Device Manager and double-click on the sound card.
   
3. Go to the tab intelligence, find the section properties and select an item from the list Equipment ID and several values ​​will appear, we will need the first one first. Copy it.
4. Next, go to the website devid.info, enter this value into the search bar and click Search.
5. This site will select the most suitable driver for us and we will only have to download the latest version for our operating system.
   
6. After downloading the driver, run the installation file if available.
   
7. If the driver was downloaded in some other format, then it is installed a little differently, you need to use the task manager, click on the Driver tab Update.
   
8. After that, search for drivers using the built-in program.
   
9. Click browse and indicate the path where the driver is located. Click next.
   
10. The installation will be completed and the driver version will be updated upon completion.
    

But installing a driver for sound is not all.

For those who have a sound card Realtek, and almost everyone has it, I recommend installing an auxiliary program.

It's called RealtekHigh Defender Audio Driver. It helps a lot when working with sound. If, for example, there is no sound on the computer, then again after installing Realtek High Defender Audio, the problem can most likely be solved.

Download Realtek and install.

The installation takes place in two stages: first, the program copies the necessary files and warns that the computer will reboot, and after the reboot, the driver fully continues its installation.

Once the installation is complete, the computer will need to be restarted again for all the changes to take effect.

As a result, we will see a new icon next to the volume control, this is a small column that indicates that the program is already running.

You can run it and you can even make some settings, but more on that in the next article.

5. Connection to a computer

If the sound still doesn’t work, then here’s another reason that comes up from time to time. Here is his solution.

Unfold the system unit and check that the cable from the speakers is completely inserted into the corresponding connector.

Almost always it is highlighted in green; this is the speaker connector. Check that the cable is firmly inserted into this connector. And in general, to be on the safe side, I advise you to pull it out again and reinsert it again.

6. Windows Audio Service

Sometimes it happens that the sound disappears due to a service failure. Let's check that everything is okay there.

7. Checking the speakers

Of course, you’ve already checked 100 times, turning the volume controls on the speakers, but I can’t skip this point, because it happens that somewhere the wiring came loose, they forgot to insert the speakers. Or let’s say the headphones are broken and the like. And the user immediately panics, what to do, there is no sound, what happened.

Connect the speakers that have no sound to another computer or laptop. This will be much more reliable; if you do this procedure, then you will be 100% sure that your speakers are not broken, it will be much easier. The same applies to headphones, if there is no sound there either.

8. Setting up sound in BIOS

This step is for those who have recently made some changes to Bios. If you changed something in Bios, then there is a chance that you accidentally disabled the function that is responsible for sound.

9. Viruses

If you have some kind of hard virus, then it is 100% that it harmed our computer.

You need to remove all malicious programs. Well, of course, the sound rarely disappears due to viruses, but this also happens, so this step also needs to be worked out

10. System recovery or reinstallation of Windows.

If you suddenly lost sound on your computer or laptop, and you even know what day it happened or after what operation, then you can return everything to its place by performing a system rollback.

There is such a cool feature as system recovery. Below are instructions on how to start it.

And in the saddest cases, when system restore did not help or was completely disabled, then reinstalling Windows can help you. This seems to me to be the latest attempt to restore sound on the computer

Nothing helped

I hope you've worked through all 10 steps thoroughly before you get to this point.

But if you have done all this, and nothing helps you, then all that remains is to take the computer to a specialist and let him take a look at you. Most likely your sound card is broken and will need to be replaced.

In any case, I ask you to write in the comments how you managed to solve the sound problem on your computer. I wish you good luck.

Hello.

I never thought that there could be so many problems with sound! It is undeniable, but it is a fact - a fairly large number of laptop users are faced with the fact that at one point the sound on their device disappears...

This can happen for various reasons and, most often, you can fix the problem yourself by delving into the Windows and driver settings (thanks to which you can save on computer services). In this article, I have collected some of the most common reasons why sound disappears on laptops (which even a novice PC user can check and fix!). So…

Reason #1: Adjusting the volume in Windows

I, of course, understand that many may express dissatisfaction - “ that this is really..." for such an article. But still, many users do not know that the sound in Windows is controlled not only by the slider, which is located next to the clock (see Fig. 1).

Rice. 1. Windows 10: volume.

If you click on the sound icon (located next to the clock, see Fig. 1) with the right mouse button, several additional options will appear (see Fig. 2).

1. volume mixer: it allows you to set your own volume in each application (for example, if you don’t need sound in the browser, then you can turn it off there);
2. playback devices: in this tab you can choose which speakers or speakers to play sound through (and in general, this tab shows all the sound devices connected to the device. Moreover, sometimes even those that you don’t have! Can you imagine, sound can be supplied to non-existent devices ...).

IN volume mixer Pay attention to whether the volume in your running application is turned down to a minimum. It is recommended to raise all sliders up, at least while troubleshooting and troubleshooting audio problems (see Figure 3).

In the " Playback devices» please note that you have there may be several devices(I have only one device in Fig. 4) - and if the sound is “sent” to the wrong device, this may be the reason for the loss of sound. I recommend that you check all the devices displayed in this tab!

Rice. 4. Sound/playback tab.

By the way, sometimes the built-in Windows wizard helps you figure out and find the causes of sound problems. To launch it, just right-click on the sound icon in Windows (next to the clock) and launch the corresponding wizard (as in Fig. 5).

Rice. 5. Troubleshoot audio problems

Reason #2: drivers and their settings

One of the most common causes of problems with sound (and not only with it) is conflicting drivers (or the lack thereof). To check their availability, I recommend opening device Manager: To do this, log in Windows control panel, then switch the display to large icons and launch this manager (see Fig. 6).

Next, open the “ Sound, gaming and video devices". Pay attention to all lines: there should be no yellow exclamation marks or red crosses (which mean there are problems with the drivers).

By the way, I also recommend checking the drivers in the Driver Booster utility (there are both free and paid versions, they differ in speed). The utility quickly and easily helps you check and find the necessary drivers (an example is shown in the screenshot below). What’s convenient is that you don’t need to independently search on various software sites, the utility itself will compare the dates and find the required driver, all you have to do is click a button and agree to install it.

Article about programs for updating drivers: (including Driver Booster)

Reason #3: the sound manager is not configured

In addition to the sound settings in Windows itself, the system (almost always) has a sound manager, which is installed along with the drivers ( in most cases this is Realtek High Definition Audio). And quite often, it is there that non-optimal settings can be set that make the sound inaudible...

How to find it?

It's very simple: go to Windows control panel, and then go to the “ Equipment and sound". Next on this tab you should see the manager that is installed on your equipment. For example, on the laptop that I am currently setting up, the Dell Audio application is installed. This software needs to be opened (see Fig. 10).

Another important point: you need to check whether the laptop correctly detects the device connected to it. For example, you inserted headphones, but the laptop did not recognize them and does not work with them correctly. Result: no sound in the headphones!

To prevent this from happening, when you connect the same headphones (for example), the laptop usually asks if it has identified them correctly. Your task: to indicate to him the correct sound device (which you connected). Actually, this is what happens in Fig. 12.

Reason #4: The sound card is disabled in the BIOS

On some laptops, you can disable the sound card in the BIOS settings. This way you are unlikely to hear sound from your mobile “friend”. Sometimes BIOS settings can be “accidentally” changed by inept actions (for example, when installing Windows, inexperienced users often change not only what is needed...).

Actions in order:

2. Since BIOS settings vary depending on the manufacturer, it is quite difficult to give universal instructions. I recommend going to all the tabs and checking all the items that contain the word “Audio“. For example, Asus laptops have an Advanced tab, in which you need to switch the High Definition Audio line to Enabled mode (i.e., turned on) (see Fig. 13).

Rice. 13. Asus laptop - Bios settings.

Reason #5: lack of some audio and video codecs

Quite often the problem occurs when trying to play a movie or audio recording. If there is no sound when opening video files or music (but there is sound in other applications), the problem is 99.9% related to the codecs!

• first remove all old codecs from the system completely;
• then restart the laptop;
• reinstall one of the sets proposed below (you can find it at the link) in full advanced mode (this way, you will have all the most necessary codecs in your system).

Codec sets for Windows 7, 8, 10 -

For those who do not want to install new codecs on the system, there is another option: download and install a video player, which already contains everything you need to play files of various types. Such players are becoming quite popular, especially recently (and no wonder, who wants to suffer with codecs?!). You will find a link to an article about such players below...

Players that work without codecs -

Reason #6: sound card problem

The last thing I wanted to dwell on in this article is the problems of the sound card (it can fail due to sudden surges in electricity (for example, during lightning or welding)).

If this happens, then in my opinion, the best option is to use an external sound card. Such cards are now available at a price ( especially if you buy it in some Chinese store... At least it’s much cheaper than looking for a “native” one) and are a compact device, slightly larger than a regular flash drive. One of these external sound cards is shown in Fig. 14. By the way, such a card often provides much better sound than the built-in card in your laptop!

PS

This is where I end this article. By the way, if you have sound, but it’s quiet, I recommend using the tips from this article:. Good luck!

If there is no sound on the laptop, the user will most likely not be happy. The cause of the problem can be a variety of factors. For example, the speaker system, sound card, software or motherboard may be faulty.

Software failures

There is no point in talking about hardware failures, since it is unlikely that the average user will be able to fix them. It's worth discussing a software failure. The sound on the laptop disappears mainly due to glitches in the software part of the device. If you have lost sound on your computer, you can also turn to some professional forums where specialists are quite capable of solving your problem.

What to do

So, first of all, you need to carefully check the operation of a service such as Windows Audio. In order to get into it, you should find the “Services” sub-item in the “Administration” item. You can find it in the control panel. In the new window that opens, you should find the necessary service that can help if there is no sound on the laptop. Once you open it, you will need to check its status whether the “Launch” button works or not. If the status indicates that the service is not running, click on “Start”. It is also important to pay attention to the launch type: it must be automatic. If this is not the case, everything needs to be corrected. After this, the service window can be closed.

It's worth checking if the driver is installed

Then you need to go back to the control panel and go to the “Sounds and Audio Devices” tab. In it you need to open the “Volume” item. If the sound on the laptop is lost due to the software part, then you will be able to see a record that the required device was simply not detected. After this, you should go to the “Device Manager”, which is located at “My Computer” - “Properties” - “Hardware”. In the window that opens, you need to open the “Sound Devices” tab. If the driver is missing, this tab will most likely be marked with a yellow icon.

Driver installation

Often, when the sound on a laptop disappears, you will simply need to install a special sound driver. It usually comes on a disk with your computer. But if it is not there, then the program can be downloaded from the Internet. You can again install the driver in two ways - manually or automatically. It is installed manually through the Setup file. If you choose this option, you will have to independently search for the root directory for installation and some other types of settings. You can install the driver automatically through Device Manager. To do this, you just need to click “Update drivers” on the appropriate tab and follow the simple tips. It is worth knowing that after installation you will need to restart your computer. If everything went as it should, then the sound should appear. It can be configured in the same “Volume” tab. There you can adjust it the way you need it.

Conclusion

It is also worth understanding that although this problem happens often on the XP operating system, this does not mean that it does not occur on other systems. Recently, more and more often on forums you can see the following messages: “The sound has disappeared on the laptop - Windows 7. What should I do?” As you can see, no one is immune from this problem.

If you encounter a problem where there is no sound on your laptop, you should consistently check the main possible causes of this malfunction.

1. Volume is turned off in settings.

To check if the sound is muted directly in the volume settings. To do this, you need to pay attention to the speaker icon next to the clock in the lower right corner of the screen. Left-click on it and look at the volume level.

2. Laptop speakers are disabled.

To check if your laptop's speakers are disabled in its settings, you should right-click on the speaker icon. Next, you need to select the “Sound” menu item and in the window that opens, select the “Playback” tab.

The playback settings window will display a list of available devices for audio playback. You need the "Speakers" item. Make sure there is a green checkmark in the corner of the speaker icon to indicate that the speakers are on. If there is a red arrow there, you need to turn on the speakers by right-clicking on the icon and selecting “Enable”.

3. Check that the Windows Audio service is enabled

To check if the Windows Audio service is enabled on your laptop, you need to launch the Services window. You can do this by typing the word services.msc into the command line (Start - Run). In the list of services you need to find Windows Audio and check that its status is “Running”. Otherwise, you can enable the service by right-clicking on its name and selecting “Properties”.

In the window that opens, you need to click on the “Run” button and click the “OK” button.

4. Checking driver functionality

To check whether the sound device driver is working, you need to go to the “Control Panel” and open the “Device Manager”. In the list of devices you need to find the section “Sound, video and gaming devices”, and in it - your audio card.

If there is an exclamation point icon next to it, this means that you need to update the device driver. This can be done using the driver disk supplied with the laptop or on the manufacturer’s official website.

5. Checking the functionality of the speakers

To check if your speakers are working properly, try connecting external speakers or headphones to the 3.5mm audio jack. If sound is available in them, then the reason is in the laptop speakers and you need to contact a specialist to check them.

However, if all of the above steps did not help when the sound on the laptop disappeared, you should contact
