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.
My apologies, I did seriously try to figure out how to figure this out and didn't come across anything that made any sense. So, I thought it was a kernel bug...
Your suggestion to try aplay did indeed produce sound. It is the first sound I was able to get out of this configuration ever. I attached the output of alsa-info.sh with aplay playing, and with mplayer playing and not working, and the diff. Thanks for your help, at least now I have some clue about where to look.
Well, I still don't know what you did try. This should have been clarified in the first ground. Are you using PulseAudio? If so, take a look at the mixer, pavucontrol, etc, and which output is being selected. On your machine, the first device is HDMI, not the onboard audio.
If you're using the direct ALSA API without PA, it's likely HDMI being picked up as the primary output. You can change the device init order via index module option or specify the default card number in ~/.asoundrc or /etc/asound.conf in that case.
Outstanding! You rock! I had no luck figuring out how to change the device init order via index module option, but I googled around and found that I can set /etc/asound.conf to
pcm.!default { type hw card PCH }
ctl.!default { type hw card PCH }
And, that did the trick! Now I have sound!
So, apparently I'm using the direct ALSA API without PA since mixer, pavucontrol, and pasuspender is not installed. To go back to your question of what I did try, I was running Flash, Gnome Mplayer, Audacious, and VLC. I guess I neglected to mention that since the sound problem didn't seem related to the media players (they all had the same no sound problem).
Sorry about the earlier confusion. I was trying to figure out dozens of configuration files without knowing what was relevant or installed, etc.
