I certainly will try this!

This is actually true, because I started hydrogen on the same machine (the one 
with ubuntustudio) and I also have the bumpy playback there, so it has to do 
with jackd, I guess.

No, but the other PC is running with kubuntu standard, so there is no 
low-latency kernel on this system. But one question arises in my mind: I've 
read about an issue that says there might be issues with access rights to a 
low-latency kernel if you're running jackd without root rights. Does this 
issue also exists with ubuntustudio?

> does the jack shows XRUNS? 

I will get to the ubuntustudio-PC tonight, so I can't give you any 
information.
