Hmm. I'm looking for info on this, too. Not getting far ...
I'm trying to get Frescobaldi (notation) working with sound.
Mine is not motherboard sound. FWIW, timidity works, but not as a daemon.
EDIT: finally got mine working - ALSA + fluidsynth supporting Frescobaldi.
I also rebuilt qsynth for convenience.
I have discovered I was missing:
modprobe snd_seq
and
fluidsynth -i -s -aalsa /path/to/soundfont.sf2
I will package Frescobaldi and its deps when I have a chance.
