Since volume is already set high and the built-in troubleshooting was already tried, the next supported checks are the Windows sound settings and driver path.
- Check per-app and system volume levels.
- Windows 11: Start > Settings > System > Sound > Volume mixer
- Make sure both System and the affected app are turned up and not muted.
- Turn off audio enhancements.
- Windows 11: Start > Settings > System > Sound
- Under Output, select the active audio device.
- Select Audio enhancements and turn them off.
- Test audio again.
- This is important because enhancements can reduce volume or cause distortion/crackling.
- Change the default audio format.
- Go to Start > Settings > System > Sound.
- Under Output, select the audio device.
- Select Advanced.
- Under Default format, choose a different format and test again.
- Restart Windows audio services.
- Press Start, type services.msc, and press Enter.
- Right-click Windows Audio > Restart.
- Right-click Windows Audio Endpoint Builder > Restart.
- Test sound again.
- Update or reinstall the audio driver.
- Open Device Manager.
- Expand Sound, video and game controllers.
- Right-click the audio device and select Update driver.
- Restart the PC.
- If the issue continues, uninstall the audio driver and reinstall the latest version from the device manufacturer.
- Check Windows Update.
- Windows 11: Start > Settings > Windows Update > Check for updates
- Install available updates, restart, and test audio again.
If the sound is still low and crackling after these steps, the remaining supported cause is the speaker/output device itself rather than Windows settings. Testing with another output device such as headphones can help confirm whether the laptop speakers are the problem.
