Created attachment 300271 [details] asound.state from 5.10.90 where sound worked Hello, I have an arch linux system running kernel 5.10.90 that I updated today. The update brings me to kernel 5.15.14. The machine is a macmini 2,1 that is headless so I have an audio cue that I use to tell if it's up. With today's update the audio fails. The old asound.conf file has 3 sections that don't work with the new kernel. [root@ada ~]# alsactl restore -f ./asound.state.working Found hardware: "HDA-Intel" "SigmaTel STAC9221 A1" "HDA:83847680,106b0800,00103601" "0x8384" "0x7680" Hardware is initialized using a generic method alsactl: set_control:1339: failed to obtain info for control #1 (No such file or directory) alsactl: set_control:1339: failed to obtain info for control #2 (No such file or directory) alsactl: set_control:1339: failed to obtain info for control #19 (No such file or directory) The sections are 'Headphone Playback Switch', 'Speaker Playback Volume' and 'Headphone Jack'. I'm attaching my asound.conf that worked from 5.10.90 and an alsa-info.txt from both kernels in case they help diagnose this further. As with my previous bug, I don't know how to do this in one commit, so I will make 3 to add all the files. Thanks for your attention. Chris

Created attachment 300275 [details] alsa-info.sh from 5.15.14 post patch Hi Takashi, Thanks for the quick response. After a little hacking around the build system for the arch linux-lts, I applied your patch and built a new kernel. Unfortunately I still get the same errors from alsactl when trying to load asound.state, and I still get no sound from speaker-test or aplay. I am attaching a new alsa-info.sh in case you can tell what is wrong from it. If you have any other ideas, I will try them out. Chris
Ah, sorry, there was a typo in the patch, which broke the things. Please try v2 patch below.
