Hello,

I am in the Audio Production team of Fedora, we work collaboratively

with CCRMA. We need further information to find the problem.
* First, what version of jack and what version of kernel are you

using? Fedora comes with jack1, whereas the CCRMA has jack2 which

would replace jack1 if you choose so. (We are planning to import jack2

to Fedora soon.)
* What recommendations did you follow for setting

/etc/security/limits.conf? We need to make sure you didn't follow an

advise from a random link from the web. CCRMA's jack2 needs different

settings than Fedora's jack1. CCRMA's jack2  package does the

modifications in /etc/security/limits.conf automatically. Fedora's

jack1  does need some manual tweaking, as specified in

/usr/share/doc/jack-audio-connection-kit-0.118.0/README.Fedora
* What error messages do you get?
* You talked about interactions with pulseaudio but what did you end

up doing? Did you uninstall it?
I recommend joining the CCRMA mailing list, as there are many more

people there to help you. e.g. I can't help you much pulseaudio since

I always remove it from my systems, but there are people at CCRMA who

use it.

Your experience and opinion are important for us since we don't want

the initial set up to be a turndown for new users.
Thanks,

Orcan
