Sound service in windows 11 keeps “disappering” and won’t appear in services and the sound will stop. After a reboot, the service will appear and the sound will come back.
As a troubleshooting task, I would create a restore point immediately upon boot when the sound is working. Then be very observant as to what is happening when it quits. When it goes out, attempt a restore. If that works, it is in the registry or a system file. The next time it goes out, open a CMD window and type SFC /scannow. If that fixes the problem, then a system file is becoming corrupt. Now, which file and why becomes your search. Could be an HDD/SSD issue, could be loose connections, could be a PSU issue, could be a program issue.
