Asus Chromebox 3 CN65 - Debian - sound card not getting detected

I have an Asus Chromebox 3 / CN65 (with i7-8550U processor - Kaby Lake) that had MrChromebox’s BIOS installed, along with Windows 11. I’ve replaced Windows 11 with Debian 12 + Gnome. I had posted an issue Asus Chromebox 3 CN65 - Debian - audio jack not working earlier back in December - and @WeirdTreeThing’s reply fixed the audio as well.

Unfortunately, I re-installed gnome yesterday by mistake - and now the sound cards are not getting detected! Please help. I’ve tried the steps mentioned in the link above but nothing seems to work.

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

lspci -v

I have run debugging.sh but am not able to attach the gz file here. Please let me know how I can send it

I’ve fixed the sound card issue by doing updates. The audio is working, but the mic is still not functional, though it gets detected

I was able to get the mic working later that day. Facing an odd issue with my setup. I shutdown and restart my CN65 desktop everyday. The audio and mic get detected on some restarts, and don’t get detected at other restarts. Any idea what the issue could be?
