Hi, I have issue with microphone in ASUS Chromebook C201. It is an RK3288-C SoC and built-in sound card is called VEYRON-I2S. Sound works perfectly on both speakers and headphones. However there is no microphone input, arecord gives silent stream (pulseaudio is disabled). In alsamixer "Int mic" and "Headset mic" are set to "On". I am running mainline kernel 5.4.6 and Debian testing. Is microphone known to work with this hardware ? If so, how to make it working ?
Thanks in advance, Tomasz Jeruzalski
