Remove audio from audio devices and sounds in settings
This was posted from another user, and I have the same problem. "I downloaded iShowU Audio capture on my Mac, then I deleted the app, and all the files that are related to that app, but the device "iShowU Audio capture" is still there in the sound input, and whenever I want to talk to someone, the mic don't work. Also, I can't remove "iShowU Audio capture" from sound input, so how can I delete it ? ."
