Yes, thats right, but using the jackstart program provied in Planet CCRMA
you can run jackd as a normal user.

Try creating a shell script, eg /usr/local/bin/run-alsaplayer:
---- cut -----
#!
alsaplayer -o jack $* || alsaplayer $*
---- cut -----
then do:
# chmod 755 /usr/local/bin/run-alsaplayer
Then set that as the association, it will try to run under jack, then if
that fails fall back to alsa.

I haven't really used jackstart much, but when I did it dodn't seem to
give me such solid performance, but that was a while ago, so maybe there
was a bug.
Running all our audio apps as root isn't really a good long term
solution.
