Title: How to restore sound to your computer
When using your computer on a daily basis, it can be disturbing to suddenly notice that the sound has disappeared. Whether you're watching videos, listening to music, or participating in online meetings, sound is essential. This article will provide you with detailed solutions to help you restore computer sound quickly.
1. Check the hardware connection
First, make sure all hardware connections are working properly. The following are common hardware problems and their solutions:
| question | Solution |
|---|---|
| Speakers or headphones not plugged in | Check that the plug is securely inserted into the audio connector (usually the green connector). |
| Volume control button off | Check that the volume buttons on your speakers or headphones are turned all the way down or muted. |
| Equipment damaged | Try changing to other speakers or headphones to test. |
2. Check the system volume settings
If the hardware connection is normal, there may be a problem with the system volume settings. Here are the steps:
| operating system | Operation steps |
|---|---|
| Windows 10/11 | 1. Right-click the volume icon on the taskbar. 2. Select "Open volume mixer". 3. Make sure that the volume of all applications is not muted or turned down. |
| macOS | 1. Click the volume icon on the menu bar. 2. Drag the slider to adjust the volume. 3. Check whether the output device in Sound Preferences is correct. |
3. Update or reinstall the sound card driver
Sound card driver issues are also a common cause of missing sound. Here's how to fix it:
| steps | Operating Instructions |
|---|---|
| Check driver status | 1. Open Device Manager (Windows) or System Information (macOS). 2. Find "Sound, video, and game controllers" and check if there is a yellow exclamation mark. |
| Update driver | Right-click the sound card device and select "Update Driver". |
| Reinstall the driver | After uninstalling the current driver, restart the computer or download and install the latest driver from the official website. |
4. Check whether the audio service is running
If the audio service of the Windows system is not started, it will also cause silent problems. Here's how to check:
| Operation | steps |
|---|---|
| Open service manager | 1. Press Win + R, enter "services.msc" and press Enter. 2. Find the "Windows Audio" service. |
| Start service | Right-click the service and select "Start" or "Restart". |

Sometimes the computer may mistakenly select a different output device (such as a virtual device). Here's how to adjust:
| operating system | Operation steps |
|---|---|
| Windows | 1. Right-click the volume icon and select "Sound Settings". 2. Select the correct device (such as speakers or headphones) in Output. |
| macOS | 1. Open System Preferences > Sound. 2. Select the correct device in the Output tab. |
6. Try system restore or reinstall the system
If none of the above methods work, the system file may be damaged. You can try:
| Operation | Description |
|---|---|
| system restore | Restore to a previous system restore point with normal sound (Windows). |
| Reinstall the system | As a last resort, back up your data and then reinstall the operating system. |
