Hi Rosea,

What I've been doing for my laptop for work related reasons (my desktop is running pure Ubuntu Studio Hardy) is that I install following packages:
etc. audio apps I need (I compile most recent Ardour always but the repository version should be also fine although it's not too fresh all the time)

Then I edit my /etc/security/limit.conf and add lines:
@audio  -       rtprio          99
@audio  -       memlock         256000
@audio  -       nice            -10

Also you should set dev.rtc.max-user-freq=1024
you can do that by adding the line to /etc/sysctl.conf
If that does not persist after reboot you can try setting it on every boot by using for example rcconf tool (you are propably able to google that method up. It involves creating a simple script and setting it to execute on every boot with rcconf)
