When the computer has no sound, first check the basic settings: make sure that the system is not muted, the volume is normal, and the output device is correct; then update or reinstall the audio driver; then run the system's own sound troubleshooting tool; finally check whether the Windows Audio-related services are running. Sequence checks can usually solve problems quickly.

There is no sound in the computer, and many people's first reaction is to try restarting. But in fact, the problem may not be that complicated, and most of the time it can be quickly investigated and solved. The following common situations and corresponding methods can basically cover common silent problems under Windows 10 systems.

Check basic settings: mute, volume and output devices

Let’s confirm the simplest points:

• Is the system muted? Is the volume icon in the lower right corner of the taskbar slashed?
• Volume is turned too low? Sometimes I accidentally press the shortcut key to turn off the volume.
• Have you selected the sound output device correctly? For example, if you plug in the headphones but use the speaker, or if you don't switch back when you connect to the external speaker.

The operation method is very simple:
Click the volume icon in the lower right corner of the taskbar → select "Sound Settings" → click "Sound Control Panel" or directly view the current default playback device in "Sound Settings". If there are multiple devices, click on them one by one to try.

Update or reinstall audio drivers

Many silent problems are caused by drivers, especially compatibility issues that are prone to occur after updating the system.

You can handle it like this:

• Open "Device Manager" (Win X → Device Manager)
• Expand "Sound, Video, and Game Controllers"
• Right-click your audio device (such as Realtek High Definition Audio) and select "Update Driver"
• If the update is invalid, try "Uninstall the device", and then restart the computer and let the system automatically reinstall

If you are not sure which is the correct audio device, you can save the list screenshot first to avoid mistaken deletion.

Troubleshooting the sounds that come with the operating system

Windows 10 has a built-in gadget that can automatically detect and fix some basic problems.

Operation path:

• Settings → Update & Security → Troubleshooting
• Find the "Play Audio" option → Click "Run Troubleshooting Tool"

It will automatically check for obvious problems, such as the service not being started, the device being disabled, etc., and give suggestions.

Check whether the system service is running normally

Sometimes, if Windows Audio-related services are not started, it will also lead to no sound.

The steps are as follows:

1. Press Win R to enter services.msc to enter
2. Find the "Windows Audio" service in the list
3. Check whether the status is "Running". If not, right-click and select "Start"
4. Also check whether the "Windows Audio Endpoint Builder" service is enabled

If you are not familiar with these operations, you can also directly search for keywords related to "recover audio". The system usually recommends the corresponding troubleshooting portal.

Basically these commonly used methods. In most cases, checking it in sequence can solve the problem. Sometimes it is not a big problem, but it is easy to ignore details, such as inserting the wrong interface, selecting the wrong device, or just needing to restart the audio service.
