Hey All,

I just upgraded to Fedora 9 and am finding that Jack won't start in realtime
mode as a normal user.  It starts fine with realtime as root.
The only thing I know to check is the /etc/security/limits.conf file.  Mine
looks ok I think:

## Automatically appended by jack-audio-connection-kit
@jackuser - rtprio 20
@jackuser - memlock 4194304

## Automatically appended by jack-audio-connection-kit
@pulse-rt - rtprio 20
@pulse-rt - nice -20


Any ideas why Jack won't start with realtime priority as a normal user?
I use qjcakctl.
kernel: 2.6.26.8-1.rt12.2.fc9.ccrma.x86_64.rt #1 SMP PREEMPT RT
Jack:
jack-audio-connection-kit.x86_64
0.116.1-3.fc9

jack-audio-connection-kit-example-clients.x86_64
0.116.1-3.fc9

jack-rack.x86_64
1.4.7-1.fc9

jackmix.x86_64
0.4-1.fc9.ccrma

qjackctl.x86_64

Thanks a lot,
