this happens because when something just works somebody at ubuntu feels the uncontrollable urge to mess things up...

explanation:
in ubuntu 10.04 developers have moved the nice values related to audio priority from the limits.conf file to the /limits.d/audio.conf file BUT they didn't update the jack audio connection kit package accordingly.

workaround:
navigate to /etc/security/limits.d/audio.conf file, open it, copy the desired nice values, go one folder back, open the limits.conf file, paste the values in the file and save it. start jack. done.

solution: update the jack audio connection kit package OR move the nice values back to the limits.conf file.

I not see /etc/security/limits.d/audio.conf file in my case. Can you please this nice values here?

[Trekkele (trekkele)]

the values are:

@audio - rtprio 100
@audio - memlock unlimited
@audio - nice -10

just copy-paste them into /etc/security/limits.conf file and have fun ;)

Hi, that is my PPA ;)

I know jack 1.9.6 has been out recently,
maybe someone could package it for the official repos with a fix for this?

In my PPA, I use a special jack2+LADI branch (jack v1.9.6 + fixes)
see ladish.org for info about LADI

JACK package in Maverick is fixed, but I think backport fix to Lucid is necessary. Now in Lucid JACK just not work.
