[PlanetCCRMA] problem starting jackd on FC6

[Brian Herrmann]

  I have installed Fedora Core 6 and while waiting for Planet Core FC6 
to be built was just messing around. I realized however, that I would 
need a few things not available from Fedora extras like alsa-tools and 
alsa-firmware to get my HDSP Multiface up and running.  Fortunately, I 
was able to install the Planet FC5 rpms without problem and did not have 
to resort to building from source, etc.   So good, so far.

 Somethings like the jack-audio-connection-kit and Qjackctl are 
available from FC6 extras and so, I installed them thinking to see what 
sort of performaceand whatever else I could get going with the base 
system, but trying to start jackd using Qjackctl I get this:

01:14:00.664 JACK is starting...
01:14:00.665 jackd -R -dalsa -r44100 -p1024 -n2 -D -Chw:0,0 -Phw:0,0 -H
01:14:00.679 JACK was started with PID=3342 (0xd0e).
jackd 0.102.20

01:14:00.881 JACK was stopped successfully.
01:14:02.693 Could not connect to JACK server as client. Please check 
the messages window for more info.

 From the terminal:

$ jackd -R -d alsa -d hw -r 44100 start
--copywrite stuff..

Well, I guess that sort of answers my own question.... No R/T patches no 
--realtime-priority option for jackd?

Am looking at Qjackctl, qjackctlrc (and looking for .jackdrc and not 
finding)  and how to remove option -R

Anyway, time to change the strings on the classical guitar...a different 
kind of problem. Nice to have choices!
