Hi Nico,

it seems more kernel config options are missing. Distribution kernels typically enable all the machine drivers, but you are specifically missing CONFIG_SND_SOC_INTEL_SKL_HDA_DSP_GENERIC_MACH=m
I've enabled this one and all machine types and indeed the card is being recognised (report at http://alsa-project.org/db/?f=5cbe7c293cbb80ab548b892cfc8b991476b0b2aa). I checked permissions on /dev/snd, which looks good.
However, obs does not list the microphone at all and chromium / jitsi shows the snd-hda-dsp mic, however does not let me select it.
ok, that's great so the driver appears to work now. You could try to do simple arecord test in terminal:
arecord -fdat -vv -Dplugw:0,6 -c4 /dev/null
That does not work:
[15:55] nb3:~% arecord -fdat -vv -Dplugw:0,6 -c4 /dev/null ALSA lib pcm.c:2660:(snd_pcm_open_noupdate) Unknown PCM plugw:0,6 arecord: main:830: audio open error: No such file or directory
However, recording with audacity produces to results:
- no sound recorded by default - sound recorded when I plugin an external headset
And using arecord -fdat -vv -c4 /dev/null (without -Dplugw) I get output, but the level is always 00% without the headset, ranges 02 ~ 90% with the headset plugged in.
I was wondering if there's a hardware switch "broken" for the detection of the headset and that's why the mic is muted internally?
