I've posted this previously. I'm having sound problems again. I've been switching to running as Administrator in order to play Microsoft Solitaire Collection games which don't play while running normal Win 10. Today, I played Solitaire as Administrator with normal sound, but when returning to the regular Win 10, the sound was gone. Normally restarting restores the sound, but this time the sound didn't restore. I'm not even getting the normal Win 10 startup chimes.

I installed a Windows update yesterday, i.e. March 24, 2020—KB4541335 (OS Builds 18362.752 and 18363.752)

There is an option to restore previous settings,... worth doing?




These settings are reported as working properly.

Suggestions for restoring sound?

Edit: Ran the troubleshooter for sound, rebooted as required, bot still no sound.
