If the system sounds are not loud, you can check the following steps: 1. Check the default playback device and volume settings, confirm that it is not muted and the volume is normal, and make sure that the system sound is not muted separately; 2. Enable the system sound theme, set the sound scheme to "Windows Default"; 3. Restart the "Windows Audio" service and set it to automatically start; 4. Update or reinstall the audio driver, restart after uninstalling and let the system automatically reinstall; 5. Run the sfc /scannow command to repair possible corrupt system files. The above methods basically cover common problems and can be gradually investigated and solved.

The system sound suddenly stopped ringing, especially when you rely on prompt or notification sounds, it is really crazy. On Windows 11, although this problem may not be a major fault, it is sometimes quite confusing to troubleshoot. The key is to confirm whether the sound service, device status and system settings are all normal.

1. Check the default playback device and volume settings

If the system sounds unsound, you must first confirm whether the sound output device is not selected correctly or the main volume has been muted.

• Click the volume icon in the lower right corner of the taskbar to confirm that it is not muted and the volume slider is not set to the lowest level.
• Right-click the volume icon, select Sound Settings, go to the Sound Control Panel or Sound Settings page, and make sure the "Default Device" is the headset or speaker you are using.

Sometimes the system sound is controlled separately. You can open "Sound Settings" → "Sound Effects and Sound Control Panel" → Find "Program Volume and Device Configuration File" and check whether the "System" item has been muted or adjusted to 0.

2. Check whether the system sound theme is enabled

Windows 11 allows you to turn off the system sound prompts completely, and there will be no prompt sounds even if the volume is normal.

• Open Settings → System → Sound.
• Scroll down, find the Sound Effects section, and click Sound Control Panel.
• In the Sound tab, make sure that Play Windows Announcement Sounds and Sound Schemes are selected for Windows Default.

If you switched to "Silent" or other customization schemes before, restoring the default settings will usually solve the problem.

3. Ensure that the Windows Audio service is running normally

System sound depends on background services, and if the "Windows Audio" service is disabled or stopped, it will also cause the sound to fail.

• Press Win R , enter services.msc , and enter.
• Find "Windows Audio" in the service list.
• Right-click to select “Restart” service. If the status is "Stopped", click "Start".
• At the same time, check whether the "start type" is "automatic". If not, it is recommended to change to automatic to avoid problems again when the next startup is started.

If the restart service is invalid, you can also try to restart the computer. Sometimes temporary problems will be solved after restarting.

4. Update or reinstall the audio driver

The driver is corrupt or outdated, which may also cause abnormal system sounds.

• Press Win X and select Device Manager.
• Expand Audio Input and Output or Sound, Video and Game Controller.
• Right-click on your audio device (such as Realtek High Definition Audio) and select "Update Driver".
• If the update is invalid, you can try "Uninstall the device" and then restart the computer, and the system will automatically reinstall the driver.

If you are not sure which device to update, you can uninstall all audio devices before restarting to allow the system to re-identify.

5. Check whether the system files are corrupted

If none of the above methods work, it may be that there is a problem with the system file.

• Open a command prompt (administrator permissions).
• Enter the following command and press Enter:

   sfc /scannow

• Wait for the scan to complete, if there are any corrupt files, they will be automatically repaired.

This process may take several minutes, and after completion, restart the computer to see if the problem is solved.

The system is not loud, which is often a minor problem, but it takes a step-by-step process to troubleshoot. From the most basic volume settings to services, drivers, and then to system files, these are basically the places where problems may occur. It is not complicated but easy to ignore, especially the system sound theme and service status, which many people will not think of at the first time.
