Sound Preferences pane freezes hangs and Erroe appears
I have just had this same problem. I booted up on Safe Mode and can get sound working and Sound Preferences appears fine. However, when I switch back to normal mode, it goes back to sound not aorking and Sound Preferences hangs freezes causing me to Force Quit. See attached.
I too had CleanMy Mac installed. Should I remove that App?
I reinstalled Monterey and the problem persists.
What is the best solution to this?
