Hi Sasha,
there seems to be several problems here.
1. starting muse w/o jack
2. starting jack with sudo, with -d hw:0
3. starting jack without -d hw:0
-----
Number 3 would probably work better if you added the -d hw:0
Number 2... I've never tried to sudo it, try as "normal" root. Though the
errors you get may suggest that there is something wrong with your
soundcard-setup.
Number 1... well, the data printed suggests your card is severely
misconfigured... I have no good clues to what may be the problem.
What is in your /etc/modules.conf?
What other programs have you gotten to work that proves that audio works?
