> Skylake, Kabylake, Kabylake-refresh, Amberlake and some other platforms where audio is of SPT (PCH) type, HDA (with DSP capabilities) plus DMIC configuration is supported on these with skylake driver since kernel 5.8. However, no sound card can be detected w/o the topology binary file in /lib/firmware and corresponding ucm file.

And the topology binary file and UCM files need to be located in the correct path based on Intel's suggestion. https://gist.github.com/crojewsk/4e6382bfb0dbfaaf60513174211f29cb.
