pacmd doesn't work with the system mode, but that's not a problem, just
use pactl instead. pactl is better than pacmd anyway.

Can you attach the output of "paplay -v test.wav"?

If you stop pulseaudio, does "aplay -Dplughw:0,0 test.wav" work? If it
doesn't, it's probably an alsa problem.

Well, Liberapay is an alternative to Patreon: 

Both Liberapay and Patreon are meant for supporting my general
maintaner work, so they are not a way to get me work specifically on
your problems. That's consulting work, and unfortunately I don't have
time for it (but I may respond to simple questions on the mailing list,
like this one).
