Comment # 13 on bug 1230496 from Takashi Iwai

This seems forgotten in the last weeks.

To be sure, the problem still persists with the latest TW or Slowroll kernels,
right?

Looking at your alsa-info.sh output again, it shows that the HD-audio device
got bound and configured, and it appears OK, per se -- even without Nvidia
workaround.

Which sound are you testing?  Doesn't the headphone output work, either?
And, how exactly are you testing?  How about below?

% aplay -vv -Dplughw:1 /usr/share/sounds/alsa/test.wav

If you're using pipewire, try to disable the audio via

% systemctl --user stop wireplumber

and resume the audio after test via

% systemctl --user start wireplumber
