[why not run realtime Jack as root? you may ask... on my setup, with the new shm version of Jack, running it as root makes a logfile in the /dev/shm directory which not only jams up the Jack/Alsa communication somehow, but also prevents an ordinary user from starting Jack until this logfile is removed. don't know if this is the case for any of the rest of y'all.] best + thx again everybody for a very informative thread, derek
