I just had a similar experience. I had installed the ubuntustudio-audio and audio-plugins metapackages and linux-rt kernel on Fluxbuntu 7.10 RC. I got the same QJACKCtl error. I had already made myself part of the audio group. I searched the forums,found the tip about /etc/security/limits.conf and made those changes, but still no success. Some further investigation showed that QJACKCtlcould not access /dev/shm if I ran it as myself. If I ran QJACKCtl using sudo, no problem. Unfortunately that is where my investigation ended. I installed Xubuntu and the ubuntustudio stuff and all is well. I should probably post to the Fluxbuntu forum as well...
