[linux-audio-user] Problems starting JACK...

Hi all, I wondered if anyone could help me. I'm having problems starting JACK from Qjackctl. I'm running a current PlanetCCRMA FC3 setup, and my soundcard is an RME DIGI9636. I have appended the output which I get in Qjackctl's "messages". Does anyone have any ideas?
