No, I am not using realtime in jackd. I believe I need to recompile
the kernel or something to run it with realtime privileges; am I
wrong? About parameters for jackd, I am not sure: I use qjackctl, so I
do not directly using comand line parameters. I am running kernel
2.6.18 (optimized for 686), Debian distribution.
