How do I delete an audio device that doesn't have that option in Audio Devices? The device appears in Audio Devices, but the "minus" option is grayed. How do I remove it? It's leftover from an app I deleted a while ago, but its audio device seems to remain. I'm working on a 2017 iMac.
Never mind. Solved. For anyone with the same problem, I searched in EasyFind for "aPowersoft," deleted the six items I found, and restarted. Problem solved.
