first off check you mixer values....
right click on the speaker icon in your tray (its near the clock). check to be sure that you don't have the output muted or very low.(turn them all up and see if it works. then.. if so find out what control it is).

I've already checked that.

I think it's a driver problem (as you can see, i'd to download and compile Alsa driver). But don't know how to solve Firefox sound problem.

are you tring to get sound from the HDMI?, i have a r700 based video card (hd4830), i have never tested the hdmi (nothing to use it with).

if you using the regular sound output(maybe even w/ the hdmi) and its only firefox , i had issues with flash not playing sound when i had pulseaudio installed, i would suggest if you have it installed then you should remove it and see if that helps you.

Problem Solved:
After uninstalling pulse audio, sound works on Firefox.

The alsamixer(gui) is another good tool for solving audio problems.
