JACK in Intrepid - can't start jackd

[Guest]

I'm trying to use JACK after having done a fresh install of Kubuntu 8.10 Intrepid Ibex.

I'm using qjackctl and in my setup, I have input set to hw:0,1 and output hw:0,0 (only one sound card on my laptop)

Here's the messages I get in the messages window:

It looks like something is hogging the sound output and preventing JACK from connecting. In similar trouble, I use a program called Transcribe to slow down music I'm trying to learn by ear. It also can't connect to the sound card.

I installed e17 desktop environment the other day, and I can connect to the sound card with both JACK and Transcribe just fine. I'm guessing there's something (Phonon?) that's specific to KDE4 that's causing the problem. Any way to temporarily turn this off?
