[usersUbuntuStudio] Jack lags...

[Robert Klaar]

So, a somewhat conclusive update. I have now gotten it to work properly, it
had to do with the audio buffert and the IRQ-priority for my soundcard, both
of which I'd tested, figures the problem :), had to put the buffert
somewhere between 512 and 1024 and on top of that increase priority to my
soundcard to 80-something, anyways, now it works.

I'm looking forward to a long lasting and productive relationship with US,
currently I'm using Renoise for the most, backed up by Ardour and Hydrogen.
Cheers.
