I knew that the KDE sound system supports JACK. Not sure if this works 
directly with JACK or via aRts -> JACK. The problem currently is, that KDE's 
JACK driver doesn't support the auto startup feature of JACK: Usually you 
don't explicitly start jackd e.g. on bootup. Because you would have to decide 
with which UID the jackd process runs. So that's not good for a multi user 
environment. Instead you usually just place a .jackdrc file into the users 
home directories which contains the command line used to automatically start 
jackd when its actually needed. So if some application uses libjack and jackd 
doesn't run yet, jackd will automatically be launched with the calling user's 
UID.

If I try this with KDE (using the JACK driver), it will just tell me that the 
sound server could not be started and will be turned off. If that worked, I 
would have already switched completely to JACK. But that way I still use aRts 
for the normal desktop multimedia stuff and manually switch to JACK when 
making music.

It certainly won't. :) I don't think it will be much work to write that driver 
anyway.
