The volume level of the built-in iMac Pro Microphone appears to automatically adjust itself instead of maintaining a given volume setting. IE, set the mic volume for 25% and it will creep up much higher as it is used. I would like to disable the automatic gain control or whatever is causing this behavior. When I set the mic at a certain level, I want it to stay at that level.
