Hi Julien,

I'm having a lot of trouble getting more info on this.  mpd doesn't
work when I specify hw:0,0 but does work when I specify plughw:0,0 so
I'm trying to figure out the difference.  plughw does seem to bypass
dmix's samplerate conversion, so it seems to work just like hw.  There
must be a difference though.  Could it be documented somewhere?
