Rosegarden, Jack, opensuse 10.3

[Vedran Vucic-2]

Hello,


When I start Rosegarden 1.6.1 in Opensuse 10.3 and start jack with the command
jackd -R -d alsa -d hw:0 -r 44100 -p 1024 -n3 -i2 -o2
I got the following output:
jackd 0.109.2

cannot use real-time scheduling (FIFO at priority 10) [for thread
-1210542400, from thread -1210542400] (1: Operation not permitted)
cannot create engine


Istart it with real-time kernel.

Please advise.

Vedran

I don't know anything about SuSE (Open or otherwise) but this looks like a
classic example of a broken realtime setup.

I don't know how to fix it.  I haven't dealt with these issues in a long time,
and I know everything has changed since the last time I had any knowledge of
these matters.  Talking about what I understand to be wrong in terms of the
way things used to be would only add confusion.

Hopefully someone else can help you sort this out.

add this to /etc/security/limits.conf :

@audio - rtprio 72
@audio - memlock 400000
@audio - nice -10

also ensure that "audio" appears in the output of the command "groups"
for the user running jackd
any difference ?

Hello,

I use OPenSuse 10.3.  I removed -R option and everything works well.
It is interesting that with -R option synth plugins were not visible
in Rosegarden.
When I removed -R option Qsynth dssi plugin was visible in Rosegarden.


I will experiment more and keep you posted on any new developments.


Best wishes,

vedran
