Solved by writing

options snd_hda_intel index=1

to /etc/modprobe.d/default.conf

Thanks! I was using another workaround and then accidentally stumbled upon this thread. Your solution works like a charm
My system is Asus Q407IQ, Ryzen 5 4500U.

My workaround was from https://www.linux.org/threads/solved-as … lem.27384/ (involving hda-verb).
I still don't understand how it works but it was quite noisy, somewhat low quality, and wasn't permanent
(yes you could put it in an autorun script or cron but I'm not a fan of creating one, especially when it requires root permission and is something I don't understand - what if it b0rks something one day?!)

EDIT 220424: After some time, it only worked some of the time, and then later it started not working at all .
Leaving this edit here, seeing this post sometimes show up on google search: The hda-verb workaround seems to be legit.
After following a few chain of sources, I could find it mainlined into the kernel for some other laptop models:
