I've had tremendous success uninstalling all things Pulseaudio,
including pavucontrol. Pavucontrol has all sorts of mutes hidden in
dark, hard to reach places.

I'd suggest after uninstalling Pulse*, run alsamixer, make sure the
headphones slide is unmuted, and crank that slide up to 100%, with the
headphones off your ears to prevent ear damage. Crank master and PCM up
to 100% too. You'll probably hear the music.

If not, use amixer, aplay and speaker-test as diagnostics. I wrote a
document on troubleshooting sound systems at
http://www.troubleshooters.com/linux/sound/sound_troubleshooting.htm .
Unfortunately, I wrote it before realizing the true problems with
PulseAudio. But still, it might help.
