You should do a "yum update" after adding the CCRMA repository. Then you'll upgrade to the latest Jack:jack-audio-connection-kit.i686 0.118.0-1.fc12 @updates
jack-audio-connection-kit-1.9.4-1.fc12.ccrma.i686
You also need to config /etc/group adding your group name to 'jackuser' just like you did for video, audio, polkituser, pulse, pulse-rt, pulse-access, rtkit, cdrom, tape, and whatever else you need special access to.
After doing that you probably will need to reboot once, unless you know enough to disable and restart enough systems to get it to reread
/etc/security/limits.conf which are changed by the CCRMA Jackd. Also, you may not like the particular limits set, I changed mine to:
## Automatically appended by the Planet CCRMA jack-audio-connection-kit
## NPM changed '*' to @jackuser to limit priority escalation to jackd.
@jackuser - rtprio 99
@jackuser - memlock 4194304
@jackuser - nice -10
Also, unless you're a masochist, you should totally disable selinux ("chkconfig --level 0123456 restorcond off") by adding "selinux=0" to /boot/grub/grub.conf e.g.
kernel /vmlinuz-2.6.32.11-99.fc12.x86_64 ro root=/dev/mapper/vg_gnulem-lv_root LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=emacs2 vga=0x307 selinux=0 nomodeset 5
Above, in addition to http://old.nabble.com/uninstall-pulseaudio-to-increase-audio-app-stability-across-updates-(was-Re:-yum-update)-to27759501.html#a27759501 I also disabled the pulseaudio of video -- kernel mode setting -- and behold the glory of masses of scrolling text at bootup, stable updates, and no weird ATI radeon bugs.
Speaking of pulseaudio, http://old.nabble.com/Re:-Fwd:-jack2-p28288652.html is a potential bad interaction between pulseaudio and jack (through /etc/security/limits.conf, potential priority escalation issue).
