I've uninstalled Parallels on my Mac but the audio drivers are still installed. Where are they stored so I can remove them please? I tried /System/Library/Audio but they're seemingly not there. Thanks.
Did you remove your Parallels Access completely? The audio driver locates at /Applications/Parallels Access.app/Contents/Library/Extensions
Update: I removed them following these steps: https://forum.parallels.com/threads/how-to-remove-parallels-access-sound-1-2-audio-devices.353346
