I do now :) You're right the hda_model=17aa:38be definitely forces the tas driver to load properly (it is in dmesg) and the firmware link seemed to fix a NULL error when I first tried it.

[ 5.770034] snd_hda_codec_realtek ehdaudio0D0: bound i2c-TIAS2781:00 (ops tas2781_hda_comp_ops [snd_hda_scodec_tas2781_i2c])

I tried both 6.8.0-rc5 and then fell back to 6.7.5 because in both of these the volume control didn't work at all (seems to be at full volume), even in "alsamixer -c 1". Note that originally, the sound was low/quiet but volume control did work.
