Hi Bard, I've been looking into getting the microphone to work on some Cherry Trail + RT5645 devices with what appears to be a simple analog microphone. You can see the microphone on one of the models I'm trying to get it to work on soldered onto the right side of the PCB here: https://i.imgur.com/bJzBQWe.jpg I'm using this ucm config: https://fedorapeople.org/~jwrdegoede/chtrt5645/ Which is basically Pierre-Louis Bossart's config from: https://github.com/plbossart/UCM Adjusted because the devices all have a mono speaker. I've been trying to get this to work myself and I can get some sound while recording by adding: cset "name='RECMIXL BST2 Switch' on" cset "name='RECMIXR BST2 Switch' on" But then I mainly get noise, I do get some sound from the microphone if I talk really really loudly, but it is barely above the noise-floor. I've the feeling that BST2 is only picking up the microphone via cross-talk and that BST1 indeed is the correct input, but for some reason I get complete silence when recording when only BST1 is selected in the RECMIXR, and yes I've checked / set the "IN1 boost volume". TL;DR: I'm trying to get an analog mic to work on 3 different models Cherry Trail + RT5645 devices and I've been unable to get this to work. I've put a registerdump of the rt5645 with gnome-sound-recorder running here: https://fedorapeople.org/~jwrdegoede/rt5645-mic-red.dump Any insights / help with this would be very much welcome.
