[LAU] Jack and Suse 10.2

Hi all I just installed Zynaddsubfx, alsa modular and Specimen and some more synthezisers, on Suse 10.2 I had already installed Jack, and now also installed jackd and qjackctl I still dont hear any sound from these programs. (sound under Linux is working, LMMS and Xmms to name a few. I also installed Qjackctls. This is the message from qjackctl: 20:42:49.358 Patchbay deactivated. 20:42:49.454 Statistics reset. 20:42:49.800 ALSA connection graph change.
