Jack can not run! (Fedora 12)

Good day,
Jack do not want to start / connect and I do not now why.
When I try to run Ardor get this:

(Ardour can not start Jack…)
Using Qjackctl turn this:

(Sorry for non-English language, on the images)
Can anyone tell me how to run JACK on Fedora? (I use it only for 15 days :slight_smile:
My Fedora is, Fedora 12 32-Bit.
Thanks for help,

Is this is the generic JACK 0.116 that ships with ‘vanilla’ Fedora 12, or is it the JACK2 (1.9.4svn) that is part of PlanetCCRMA?

I just got F12 installed, and will be checking JACK2 (I’ve already put the CCRMA 1.9.4svn JACK2 in place, and really don’t have time to downgrade…).
