I am using M1 mac mini and I would like to plug in an external mic. I saw that the mac mini has only 1 audio input, and I have a USB-C to Headphone Jack Adapter. The first time I plugged this adapter in it worked and it was showned in: System Preferences -> Sound -> Input. Now it is being shown in the Output section and the mic is not working.
What USB Audio adapter do you have?
If you have a two port audio adapter, check to make sure that the microphone is plugged into the input side of the USB adapter.
If you have a single port USB audio adapter, then those are also for headsets like the Mac Mini's single audio port and you need to get a two port USB audio adapter.
I have a USB-C to Headphone Jack Adapter, with single port and I plugged it to the Thunderbolt port. Is it possible to do use the Thunderbolt port instead of the USB port?
