[PlanetCCRMA] Problems starting jack in FC2

[Per Thomas Jahr]

Hi, 

I just installed PlanetCCRMA for FC2 ealier this week but it seems I
can't start jackd. I use qjackctl to start jackd.

As root I issue the following commmand:
/etc/init.d/realcap start
Loading realcap module (allcaps=1):                  [ OK ]

Then as a regular user I start qjackctl and click start in the gui. But
I'm always getting the message "Could not connect to JACK server as a
client". And the qjackctl shows "Starting".

The verbose output in the message window of qjackctl is attached below. 

What can be wrong? I can't get realtime either for regular users.

My kernel version: 2.6.7-1.437.1.ll.rhfc2.ccrma
My sound card: ST-AUDIO ADC/DAC 2000 (ice1712)
