Today i am running in a problem after updating MAC OS, Buster is not able to select a input audio source.
The output selection does work but not the input selection. So i can not make a transmission.
In the MAC audio setup menu the podcaster is visible an the audio meter is moving when speaking into the microphone.
I updates my MACmini 2012 to level HighSierra 10.13.5
Yes i reset the NVRAM, pulled all the USB connection, pulled the power cord and waited 15 secs after restart. Reinstalled Buster......
