Follow these steps in order, since both audio and Windows Update issues can be related to drivers and pending updates.

1. Install pending Windows updates
2. Select Start > Settings > Update & Security > Windows Update > Check for updates.
3. If the status shows Updates are available, select Install now.
4. After installation, restart the PC and test the sound.
5. If updates fail repeatedly, retry after step 3 (driver cleanup) below.
6. Make sure update-related restarts are applied
7. Save work and close apps.
8. Select Start > Power.
9. If options Update and restart or Update and shut down appear, choose one to apply pending updates.
10. Test sound again after restart.
11. Reinstall the audio driver (fixes many auto‑mute/volume issues)
12. Press Win + X and select Device Manager.
13. Expand Sound, video and game controllers.
14. Right‑click the audio device (for example, Realtek High Definition Audio, High Definition Audio Device, or similar) and select Uninstall device.
15. Check Delete the driver software for this device if available, then select Uninstall.
16. Restart the PC (this will reinstall a basic audio driver automatically).
17. After restart, go back to Windows Update and select Check for updates, then install everything, including any Optional updates related to audio.
18. Try the generic Windows audio driver (if muting persists)
19. Open Device Manager again.
20. Expand Sound, video and game controllers.
21. Right‑click the audio device and select Update driver.
22. Select Browse my computer for drivers > Let me pick from a list of device drivers on my computer.
23. Select the High Definition Audio Device (generic driver), select Next, and follow the prompts.
24. Test whether the sound still mutes automatically.
25. Roll back the audio driver if the problem started after an update If sound issues started right after a driver or Windows update:
26. Open Device Manager.
27. Expand Sound, video and game controllers.
28. Right‑click the audio device and select Properties.
29. On the Driver tab, select Roll Back Driver (if available).
30. Follow the prompts and select Yes to roll back.
31. Restart and test sound.
32. If nothing works and the issue started after a recent update Use a system restore point created before the problem:
33. Open Start and search for Recovery options.
34. Use Restore from a system restore point as described in the Recovery options article to revert to a point before the audio and update issues began.

If, after these steps, Windows Update still does not complete, focus next on Windows Update troubleshooting (error codes, disk space, and update components), but the steps above address the most common combined audio + update/driver problems.
