Keep losing sound Windows 10

[Don Awalt]

For awhile now, about once or twice a week I lose all sound on Windows 10 running on my MBP/Mac OS. This happens now on Parallels 13.0.1, but it has happened prior. A restart of Windows restores sound, but this is incredibly annoying.

It happened this morning, and nothing was running over night (apps or anything I Have done I mean...) - Last night I ran Quicken, all was fine. This morning, no sound.

I have checked:
1. No errors in Device Manager
2. Parallels Audio Control is visible there and without error
3. Using Windows Sound under Control Panel, clicking 'Test' for different sounds, shows nothing. Several apps have no sound that normally do.
4. Reinstall Parallels Tools doesn't fix it (a limited test of sorts, since it does require a restart which on its own will fix it. I tried doing 'Postpone' and testing sound, and there was none).
5. No errors or warnings that appear to indicate a problem in Event Log (in fact very few errors/warnings of any type as I don't use the VM much.)

Is this a know issue, any ideas how to track down the issue, or chance it will be fixed or a config change can eliminate this problem? Thanks..

Hi there, I tried changing the Hypervisor option to "Apple", and that worked for me.

Hi Gilbert,

Thanks, in the mean while i've found this solution. And it looks like its working. Thanks for your reaction.

Unfortunately, my control panel option for hypervisor isn't editable and looks a bit different. My company locks down many settings, maybe I just don't have access?

Are you trying to activate nested virtualization? If yes, please note that the 'Nested virtualization' is available in Parallels Desktop for Mac Pro and Business Editions only. Could you please check your Parallels Desktop for Mac Edition? Also, note nested virtualization feature is not currently applicable with the Mac M1 chip. Thanks.

I'm still having this problem with Parallels 17 in December 2022.

Although I will say I just tried the "Apple" hypervisor and the sound stayed on for about an hour until I was done. That's longer than before. I'll report more.
