Does "pactl list cards" still print nothing after you've set all the
mixer settings and restarted pulseaudio?

I don't know what could be the problem if aplay can open hw:0,0 but
pulseaudio can't. Apparently there's some difference in how they
configure the device. You could study the details and differences of
the device opening and configuration sequences of the two programs.
