[PlanetCCRMA] CCRMA / Fedora 12 / jack / ffado install problem

[Niels Mayer]

FYI, I'm not using "2.6.31.12-1.rt20.1.fc12.ccrma.x86_64.rt" but rather the
stock fedora kernel
> Linux gnulem 2.6.31.12-174.2.3.fc12.x86_64 #1 SMP Mon Jan 18 19:52:07 UTC
2010 x86_64 x86_64 x86_64 GNU/Linux

Is the realtime kernel even neccesary anymore given jackd's realtime
functionality, and assuming a real soundcard with a real interrupt
(is the realtime kernel needed to get USB or firewire devices behaving , or
does it provide significant benefit for those using pci or pcie
soundcards??)

       -R, --realtime
              Use  realtime  scheduling  (default  = true). This is needed
for
              reliable low-latency performance.  On many systems, it
 requires
              jackd to run with special scheduler and memory allocation
privi-
              leges, which may be obtained in several ways.

A less drastic solution prior to fully removing ccrma's jack would be
omitting the -R flag and seeing whether the issue is an incompatibility with
"special scheduler and memory allocation privileges"... (note my unfounded
gut-feeling  that the ccrma jackd was not working compatibly alongside f12
HAL devices and special permissions needed for groups 'audio' or
'rtkit'). It may be an issue of "memory allocation privileges" -- the f12
jackd outputs "JACK compiled with System V SHM support." The CCRMA jackd
doesn't. See logs below for details.

just got him all setup with rosegarden, qjackctl, hydrogen and an Akai LPK

around with all the synths I installed:
