You need to change /etc/security/limits.conf to include:

----
## Automatically appended by the Planet CCRMA jack-audio-connection-kit
* - rtprio 99
* - memlock 4194304
* - nice -10
----

After the change you will need to logout and login again to see
changes. 

If you use the Planet CCRMA jack-audio-connection-kit package this
should have happened automagically... oh well...
