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. So with above options: - playback works - microphone does not work > Distribution kernels are a good reference when building on your own, and > we in SOF also maintain example kconfig settings for typical systems. > Here's the bit for systems with DSP and HDA codecs: > https://github.com/thesofproject/kconfig/blob/master/hdaudio-codecs-defconfig I have used the .config from the linux-edge kernel from Alpine Linux as a basis. The above configuration looks to be enabled in my .config as well. Alpine's default config might include a bit less options than other distros, I am currently in touch with the developers there for patching it, as soon as I got the sound card properly working.
