Hi!
On my computer both microphones are not working but playback and all other audio stuff seems to work. I'm not sure if the microphones ever worked with alsa because I never tried it before. On windows they are working as expected, hence the hardware seems to be OK. Is there anything I can do to further debug this? Is it a known problem?
Below you can find more information about the hardware:
