The following looks to me a regression in the linux sound driver. alsa-info.sh output is included at the bottom of this message. There are 2 outputs. An output with a 5.12.13 kernel. The other output is with a 5.15.5. They were obtained with the same PC. With 5.12.13, the speaker-test program works as expected. There is no sound when the speaker-test program is ran with 5.15.5. 5.15.5 has options snd-hda-intel id=PCH index=0 options snd-hda-intel id=HDMI index=1 , which 5.12.13 does not have.
Both those lines conflict with each other, so they make no sense and are already incorrect.
If you want to swap the card indices inevitably needed, just pass a single option line below instead.
options snd-hda-intel index=1,0
And how did you invoke speaker-test? Is it only about speaker-test and aplay works as is?
