Hello friendly UDOOers! I can't get my TRS Mic to work under linux. The jack pin-out is surely okay. And it works totally fine under Win10. But not in Debian. Please enlight me on TRRS Microphone support on linux. Is it possible to make it work? Thank you.
Just in case. My current kernel is 4.19.0-0.bpo.8-amd64. The package firmware-realtek(20161130-5) is installed.
