@Jeremy:
Thanks for the info; I'll check that wiki ASAP.

I've been also trying to get some kind of RaspMusix, but my steps are short
for now. I tried Raspbian image and then installed Ardour-arm, but Jack
didn't start although I tried to configure several times with some
parameters that usually work (including NoRT, several different periods and
frames/sec).
Another issue is that I couldn't get HDMI-audio, even making the
adjustments on the Raspberry configuration file after finding pieces of
information here and there doing some searches on the web.
So there I left with Raspbian.

Then I found RaspBMC[1] (for multimedia purpose) and it just worked
out-of-the-box.

And here I am for now. I'll try to keep reporting.
