Did you check alsamixer to ensure that the outputs are not muted ? Also
if you have pulseaudio installed, you would have to check pulse audio
mixer to ensure the sound is not muted there (or remove pulseaudio to
debug or reduce complexity).
My computer is connected via HDMI and I had to create a asound.conf to
use the audio jack instead of the hdmi audio. Do you have a similar
setup ?
