It's worth verifying that you don't have pulse audio
installed.

dpkg -l pulseaudio

Then, you can fiddle with alsamixer or aumix and raise
all the settings to full. This is the most likely issue.

If you have multiple sound cards, make sure to use
the -c argument.

The choice of kernels could also make a difference,
but AFAIK, all recent kernels have ALSA drivers for
typical builtin soundcards.

cheers,

Joel
