  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...
