Bug 216643

alsa-info generated on k6.0.6-1-MANJARO

Hi,

I have a HP ZBook Studio G5 Mobile which I use as a daily driver. I run manjaro and noticed that my internal speaker stopped working a few kernel versions ago. Sound works fine on windows. On affected versions internal speaker is not available and headphones are displayed as active.

While trying to analyze the issue, I ran into errors running hda analyzer which crashes with an error message "Invalid AFG subtree for codec Conexant CX11970?". I filed a bug here https://github.com/gm-vm/hda-analyzer/issues/1 and the author pointed to some kernel function not returning correct values (snd_hdac_get_sub_nodes)

I haven't done a full analysis of the affected versions, but 6.0.x-MANJARO seems to be affected, as well as 5.19.17-1-MANJARO. I don't have the issue on 5.15.76-1-MANJARO which I will run for the time being. I ran a couple of live usbs (fedora, manjaro) but those were not affected (I need to check exact versions but fedora was on 5.19 and manjaro on 5.15).

I am appending output of alsa-info.sh on 6.0.6-1-MANJARO.

It's been a while since I had to play with kernel stuff so feel free to send me in the right direction to provide more helpful info.

Thanks!
