  I'm running the version that came with the fedora 12 install. That
system is out in the garage, and I'm in the house right now, but I think
it reported v0.113 or something like that when it started. I'm running
one of the CCRMA kernels, I think the first one, without the PAE.

   Again, this is from memory, but it was the recommendation that jack
itself put into the qjackctl 'messages' window. I think it was something
like this:
  @audio - rtprio 100
  @audio - nice -10

   Just the above, along with something about current user not permitted to
run RT options, so I set up the limits as requested, and added myself to
the audio group.

   No that was just negative comments I read on the mailinglist. I haven't
any indication that my problems are due to PA, yet. Does fedora use PA?
That was one of the reasons I tried fedora 12, because I heard that Ubuntu
was too entangled with PA.

   I agree! The planetCCRMA @home web page was easy to follow, up until
the point that it suggested browsing the repository to select packages.
With fedora 13 only days away, why is the ccrma-audio meta-package still
only available for fedora 11?
   I also had trouble trying to install jack. qjackctl didn't draw it in,
and yum wouldn't install jack, jackd, or jackdmp. WTF is the package
called??! I finally just launched qjackctl and pressed the 'start'
button, expecting to get a message about 'jack not found' and maybe a
pointer to the proper package. I was quite surprised to see jackd start
up! It must be a part of the default fedora install. But then, I can't
seem to keep it running for more than 30 seconds...
