cant get sound to work i tired solving it with this https://www.reddit.com/r/chrultrabook/c ... flex_5_cb/ but it didnt work, i think its because it cant find any hardware playback devices for whatever reason.

and yes the sound did work when it was running chromeOS.

im on bookworm, and i installed the firmware-sof-signed package (version 1.9.1) but it still dosent work.

lspci | grep -i audio produces:
00:1f.3 Multimedia audio controller: Intel Corporation Comet Lake PCH-LP cAVS

aplay -l produces:
aplay: device_list:274: no soundcards found...

cat /proc/asound/cards produces:
--- no soundcards ---

relevant output from sudo alsa-info:
