I have no idea, but it seems like some people have it rocking, and
have asked questions about xruns, so they're at least a little farther
than you are at the moment:

I really don't know, though.  Do you have devices hw0:1? I'd do some
extensive fiddling with jackd in the command-line (my preference with
trial-and-error bullhooey)  Also, this seems like a problem:
> ALSA: cannot configure playback channel
> cannot load driver module alsa

Sorry for being curt, but I'm at work, and I must pound away like a
good little monkey. :-)
