At some point, after the May update I lost all PC audio! I've done all the 'no sound' troubleshooting suggestions from Microsoft and everywhere else. I reinstalled all audio drivers, you name it. I even shut down my MSI onboard HD audio in bios and purchased a

Soundblaster Audigy RX sound card, No dice. bought Driver Booster Pro and updated them drivers. Wasted cash!

It's as if the sound just can't get to my output jacks. Foobar doesn't work, NO audio!! You can see the level meters pulse when you test the sound devices. When I unplug the connectors going to my preamp, they pop and buzz so I know the cables to the analog stuff are hot.

I NEED HELP AND I NEED IT FAST!! I'm starting to TWITCH!! I believe it's Microsoft's doing.

    I have spend a few days trying to figure this out. Installing and reinstalling drivers. Going back to various restore points. Updating windows with repair and so on. THANK YOU! This was incredibly helpful and avoided having to do a fresh install of windows (which might still not have fixed it). Microsoft needs to figure out why this is getting wiped in some upgrades. The key change is definitely what did it.

    The powershell script worked for me just fine, but it is was missing a carriage return between the first and second command when I cut and pasted it into notepad++ for those who are trying it out.

    Also, I believe the key values are unique to individual machines and probably should not be published (mine does not match the one above), but I'm not sure what is compromised by sharing it.

    Note the change suggested by Deric McLemore brought back my audio input and output devices, but no audio. It was only the key change that worked and I had to restore the logon back to local service on the Windows Audio service before I had complete success.

    Thanks again!

    We have this issue as well, changing to Local System Account - got rid of the red x error on all reboots, however no audio could be heard. I had to switch back.

    We have several endpoints experiencing the same issue. Started after deploying May 2021 patches . After trying several proposed solutions and nothing making an impact, adding the Local Service account to the Local Administrators group. Oddly enough, if I change the "Log On" account for the Windows Audio service to the Local System, Account, then we get our Sound Adapters back.
