Hi Mikael. First I'd install Qjackctl, which is a GUI where you can get to the 
settings for jack, and also has a midi connections section.

If your soundcard is an hda intel based one, I've seen that changing the 
Periods/Buffer in Qjackctl's setup, from 2 to 3, can fix stuttery sound, and 
only last night verified that while playing something on ZynAddSubFX synth, 
where the sound was all stuttery before changing the Period/Buffer to 3.

I don't use Mplayer to play mp3's, but the above is worth a try

Nigel.
