Sound configuration (arts+alsa+jack+synth)
From Rosegarden FAQ [1]:
"Alsa? aRts? huh???"
I would like to use music editors like Rosegarden and it is very tough
to configure the environment so it can play MIDI through soft synthesis.
I could do it with "timidity -Oj -iA", but JACK is losing frames. I did
not get fluidsynth/qsynth to work with Rosegarden.
[[ I do not know if I took the right steps, though: downloaded a
soundfont from hammersound; installed fluidsynth and jackd*; killed
arts; ran "jack -d alsa" and fluidsynth -m alsa_seq -a jack font.sf2;
tried to play in Rosegarden; nothing ]]
I miss a utility that configure sound properly (all the environment, not
only ALSA) and documentation about configuring all these together
(arts+jack+alsa). I could not find any documentation about it in Debian
Reference, although AFAIK Debian docs are being rewritten for the next
release. The Linux Sound HOWTO [2] was last updated on 2001. Searching
on Google [3,4] gives many maillist messages and most recent is from
2002. Many things I found are for older kernels (2.2 and 2.4).
When I tell aRts to use JACK, at KDE startup, aRts does not find JACK. I
suppose I should call jackd at some place in KDE session start, before aRts.
In fact, my problem is: my adapter/driver (snd_intel8x0) accepts only
one channel so I need to mix channels by software; also I want to use
Rosegarden which needs synthesis. aRts seems the natural option since I
use KDE (I guess I have no other choice besides arts and esd).
Rosegarden site tells me that I need jack+{fluidsynth,timidity} and that
I should prefer fluidsynth.
I'm using kernel 2.6.7 and I have used alsaconf to set up sound card.
