I had issues with my AirPods Pro, the audio shatters while connecting to Mac, they work perfectly on other Apple Devices. Resetting Bluetooth just didn't help, I looked into the Audio Plug-In at /Library/Audio/Plug-Ins, and I noticed there were only three folders:
/Library/Audio/Plug-Ins/Components
/Library/Audio/Plug-Ins/MAS
/Library/Audio/Plug-Ins/VST
So I "deleted" folder Components by renaming it as Components.old, in case I want to recover that folder in the future. The other two folders MAS and VST were empty, therefore I didn't touch them. AirPods Pro started to work normally after a reboot of the macOS.
I'm using MacBook Pro M1, macOS 12.0.1
