Converted Chrome OS to Xubuntu 21.10 (tried 20.04) as well. All good but nod sound.
Mixer only shows dummy output. Tried some tricks from here but no luck: Fix No Sound (Dummy Output) Issue In Ubuntu With SND HDA Intel
dmesg showing error:

Try manually copying sof-bin firmware to /lib/firmware/intel/sof-tplg/ folder. See instructions in the answer of no sound due to error direct firmware load failed for intel/sof-tplg/sof-byt-max98090.tplg
