Mac mini M1 phone call sound input - corrupted or muffled
When using facetime to make a phone call "using nearby iphone" on Mac mini M1 with an external microphone (using the 3.5mm jack) connected, the input sound in the phone call gets processed automatically and at the verly least the process adds lots of gain to the point when the raw microphone signal was a a nice recording level -12 to -6 db, it is now clipping in the phone call and sounds muffled and overly conmpressed. How can we stop this automatic control over the input sound that is only happeing over "phone calls"? During normal Facetime calls, the input signal is not processed further, and sound is fine. All settings in Facetime "video" and midi set-up, and system sound are adequatly set-up for the microphone as the input. I can record nice voice signal (voice over quality more than 60 db SNR) in Garage band using the External microphone as input wihout issues.
