No sound with INTEL Comet Lake PCH cAVS and current kernel
Open, Needs More InfoPublic

Description

Hi,

on a fresh install i have no sound at all (and no microphone) with Intel Comet Lake PCH cAVS on a lenovo X1 extreme Gen 3 core I5 and GPU and audio Intel with current kernel 5.10.1-162. The audio card is not detected but it is well indicated with lspci command : 00:1f.3 Multimedia audio controller: Intel Corporation Comet Lake PCH cAVS

dmesg errors :
[ 1.875686] sof-audio-pci 0000:00:1f.3: Direct firmware load for intel/sof/sof-cml.ri failed with error -2
[ 1.875688] sof-audio-pci 0000:00:1f.3: error: request firmware intel/sof/sof-cml.ri failed err: -2
[ 1.875689] sof-audio-pci 0000:00:1f.3: error: failed to load DSP firmware -2
[ 1.881811] sof-audio-pci 0000:00:1f.3: error: sof_probe_work failed err: -2

That is a regression because all is ok with the default kernel on Solus 4.1 downloaded on the website (5.4 kernel version).

Thanks for your help

Ben

Is this still an issue with the latest kernel and alsa? We've updated alsa-lib, alsa-firmware, and linux-current since then.
