A quick look at alsa-info.sh output doesn't hit obvious issues except
for "Auto-Mute Mode" is disabled.  But this shouldn't result in the

So again, what did you test and how didn't work?

As a primary test, for example, try the following on a terminal:

  % amixer -c1 set "Auto-Mute Mode" "Enabled"
  % aplay -Dplughw:1 -vv some-your-file.wav

where some-your-file.wav is any WAV file you'd like to hear.

If you're using PulseAudio, try like below instead:

  % pasuspender -- aplay -D plughw:1 -vv some-your-file.wav

Does it play anything?  Try both the headphone plugged and unplugged.

If the above doesn't give any sound output, again give
alsa-info.sh.output captured during your test.
