Do you have all the alsa packages installed, have run alsaconf, and used
alsamixer to unmute everything and raise the volume?

I would suggest doing all that from the command line with X not running
to remove one huge variable.  Find a .wav file and play it with aplay to
verify that it works.  A command-line CD player is also helpful; I use
cdplay.

Only once the command-line tools give you sound do you then turn to
getting X apps to use sound.
