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
