Hi Craig Bui Mana,
Thank you for reaching out. When the volume icon appears crossed out and no sound plays, it usually means Windows is unable to use the selected audio device correctly. This can happen if the device is muted, disabled, not set as default, or if the audio service or driver needs to be refreshed.
In addition to Q&A Assist's answer, here's the verified list of troubleshooting steps that you can try in order to restore sound:
1, Check Volume Mixer
- Right‑click the speaker icon > Open Volume mixer
- Ensure neither the device nor the app is muted
2, Verify the output device
- Go to Settings > System > Sound
- Select the correct output device (speakers or headphones)
- Open Device properties and confirm it is not disabled
3, Restart audio services
- Press Win + R, type
services.msc - Restart Windows Audio and Windows Audio Endpoint Builder
4, Set the default playback device
- Open Control Panel > Sound > Playback
- Right‑click your speakers/headphones and select Set as Default
5, Refresh the audio driver
- Open Device Manager > Sound, video and game controllers
- Right‑click the audio device > Update driver
- If needed, uninstall the device and restart the PC to reload it automatically
You can consider using the Audio Troubleshooter
- Go to Settings > Update & Security > Troubleshoot > Playing Audio
If the volume icon remains crossed out after these steps, installing the latest audio driver from the device manufacturer’s support site can help ensure compatibility.
