Didn't you (like some other people) get into the state where pulseaudio doesn't work? It chooses as an output a dummy driver automatically, then you can change volume, play sound, but actually it all goes to /dev/null.
It took me a while before I figured out that it's a "dummy" driver I have in pulseaudio.
