Maybe this is the problem.

I think most of us are pulling the topology and firmware from the
chromeos recovery images for lack of any other known source, and it
looks a little different than this. Those can be downloaded like so:
https://gist.github.com/jmontleon/8899cb83138f2653f520fbbcc5b830a0

After placing the topology file you'll see these errors and audio will
not work until they're also copied in place.
snd_soc_skl 0000:00:1f.3: Direct firmware load for
dsp_lib_dsm_core_spt_release.bin failed with error -2
snd_soc_skl 0000:00:1f.3: Direct firmware load for
intel/dsp_fw_C75061F3-F2B2-4DCC-8F9F-82ABB4131E66.bin failed with
error -2

Once those were in place, up to 6.0.18 audio worked.

Is there a better source for the topology file?
