Ubuntustudio jack setup

Yesterday I installed a fresh copy of Ubuntu Studio 8.04
-> http://ubuntustudio.org

the default settings for jackd didn't work too well with my onboard sounddevice but I got it working after some tweaking.
Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)

so here -mainly as a reminder- are the settings for QjackCtl

my settings for Frames/Period are rather large, since I don't depend on very low latency YMMV.

NOTE: I've been told by the friendly guys in #jack on freenode that with some onboard devices 3 Periods/Buffer is preferred.

also make sure you have this in your /etc/security/limmits.conf:

@audio          -       rtprio  90
@audio          -       memlock         500000

memlock depending on how much RAM you have/want to use.
