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
--copyright stuff...
JACK compiled with System V SHM support.
cannot use real-time scheduling (FIFO at priority 10) [for thread
-1208138048, from thread -1208138048] (1: Operation not permitted)
cannot create engine
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..

apparent rate = 44100
creating alsa driver ... hw|hw|1024|2|44100|0|0|nomon|swmeter|-|32bit
configuring for 44100Hz, period = 1024 frames, buffer = 2 periods

ALSA: use 2 periods for capture

jack main caught signal 2
no message buffer overruns
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!
