    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.
