What s the matter with the laptop that no sound is there?

Isn't it too hot, the laptop is protected. Let it cool and turn it on again.

I have also encountered the landlord said that the computer has no sound problem, the reason for the infection of the virus, will also cause the computer to have no sound:

I want to perfectly solve the problem of "what should I do if the computer has no sound" and its sequelae. Please first **Keniu free antivirus,Conduct a full disk scan of the local disk,The existing malicious virus Trojan program is completely removed。

After making sure that there is no Trojan virus in the system, use the system file repair tool provided by Keniu Antivirus to carry out a comprehensive system file restoration and repair, and you can solve the phenomenon that the computer has no sound.

In addition, according to experience, the reasons for the problem of "what should I do if the computer has no sound" for many users are as follows

Check whether the sound card, cable, speaker and other devices are connected properly; Run anti-virus software for anti-virus;

If so, reinstall the driver for this device to solve the problem;

When there is no sound and no speaker, open the control panel--- Add and remove programs--- add and delete Windows components, put a check mark in front of "Accessories and Tools", click "Next", and then, shut down and restart, the system will prompt you to install new hardware, follow the prompts to install;

Uninstall the sound card driver, reinstall it or upgrade the audio driver;

When the "AC chip cannot be found" prompt appears when installing the sound card driver, it may be that the computer is poisoned, or the sound card driver has been deleted by mistake due to illegal operation, or the solution to the internal software conflict is to reinstall the system and driver.

Just ignore it, turn it off, wait for a while and then turn it back on, sometimes the sound problem will solve itself, you can try it.

Start - Control Panel - Sound & Audio Devices - Sound, see if it's set to silent, and then select Windows Default.

Click Start Run, enter regedit, press enter, this opens the registry, click a few hkey-current-user, click on the controlpanel item, and then click on the beep in the sound under it to change its value from no to yes restart, is it to hear the long-lost power on and off sound again.

Delete the original account,Create a new account,So that there is a sound on and off,It may be a problem caused by a mistake in the user profile,You can open the guest user guest first,Try to see if there is a switch sound,If so, you can use the above method,First create an administrator account,Then click on your problematic account,Then follow the prompts to delete it,In the process of deletion, it will also prompt whether to keep the files of the original account, When deleting it, it's a good idea to back up your favorites, as well as the folders created by the installer in the start menu, and then copy them back when you're done.

If there is still no sound after restarting the computer, the reason is more complicated, see the solutions below.

1. Check if the system is muted or set to a low volume.

The taskbar icon in the following image indicates that the system is muted:

Sometimes, the "Little Speaker" icon is not displayed to be muted, and the system volume is normal, but a component in the audio control is muted or the volume is low, which will also cause ** no sound. At this time, it is more troublesome to find the location of the settings, so it is recommended to reinstall the sound card driver directly, so that the audio settings will automatically return to the default state. See step 2 below.

2. Reinstall the sound card driver

In this case, you need to completely uninstall the original installed sound card and restart the computer before trying to install it.

3. The sound card is disabled.

1. If the "Little Speaker" icon on the taskbar is displayed as follows, it means that the sound card driver is not installed or has been disabled

After <>, the system will automatically find the driver or start the audio service according to the prompts, as shown in the following figure, prompting "Fixed", click "Close" to rip the cherry blossoms

2. Or right-click "Computer", and then select "Properties", then "Device Manager", if you see a downward arrow logo in front of the sound card device, it means that the current sound card has been disabled

If you want to enable, right-click the device and select Enable:

Later, the system will find and automatically complete the installation of the sound card driver.

3. If it is not repaired after this operation, it is recommended to reinstall the sound card driver according to step 2.

4. Check whether the Windows Audio Service program (Windows Audio Service) is disabled.

1. The Windows Audio service manages the audio devices of Windows-based programs. If this service is terminated, the Singing Audio Device and its sound effects will not work properly. If this service is disabled, any services that depend on it will not be able to start.

2. Click "Start", "Run" in turn, enter "and perform the recall of "Service", click "Service (Local)", find the "Windows Audio" service in the service list on the right, and you can see that the current status is not "Enabled".

3. After double-clicking to open the service, set its "Startup Type" to "Automatic", then click the "Start" button under "Service Status", and finally click "OK" to exit. As shown in Fig

4. In the figure below, the status of the "Windows Audio" service is normal.

5. If you use a quick installation system such as ghost, sometimes even if you completely uninstall the original driver and then install it with the driver recommended by the official website, it may not work normally. At this point, you can try to restore a new system test, and be sure to back up the important data on the hard drive before restoring. The way to recover the system can be either a one-click recovery or a step-by-step installation using a CD-ROM.

Hello dear o , it's a pleasure to serve you, and now it's been queried for you, Check your volume It may seem obvious, but I can't tell you how many times I've accidentally muted my volume in windows, only to pat my forehead in annoyance. Click the speaker icon in the lower-right corner of the Windows taskbar and make sure your volume is unmuted and turned up. (If you have external speakers plugged in, make sure they are also turned on and on.)

When you drag the Windows volume slider and let it go, you should hear a "ding" sound. If there is no hand with a crack, the problem is elsewhere. If you have other questions, you can continue to ask me, and I will continue to answer your questions (o).
