Hi,
I'm sure I'm nowhere near as technical as the other users on this list, but found this thread by searching about the same problem: I had sound with older kernels, but no sound with 5.15.5 (or 5.15.6). I can "see" the audio playing in equalizers like Pavucontrol, but no sound actually plays, and ALSA's speaker-test doesn't play anything either.
This is on a MacBook 2,1 with the audio device listed as "Intel Corporation NM10/ICH7 Family High Definition Audio Controller (rev 02)" and is driven by snd-hda-intel. I've set no options that I know about.
Since I've never mailed this list before, would someone mind letting me know the proper way to do a helpful test for the ALSA developers? Preferably on a live image or something like that, just so I can have as clean and helpful of an environment as possible. Again, sorry for my ignorance.
Thanks,
Paxton
