Also confirmed for HP 250 G9 (6S774EA) on ALT Linux kernels are 6.5.8, 6.1.57, 5.10.198 (which are basically usptream stable/lts branches).

Comment 2 Nick 2024-04-19 10:46:36 UTC

Same problem here: 
I is caused by a code change in patch_realtek.c

I have a working kernel based on 6.8.7 here: https://github.com/nicktelindert/linux


I reverted this commit manually: https://github.com/torvalds/linux/commit/5aec989 
This fixed the issues for ALC236. I am not sure if it breaks other systems though.
