Thank you for being so quick to answer every time! Truthfully, I don't know if there is any link between that message and my prformances... I thought so, but I have no proof!
Nonetheless the symptoms are pretty obvious : jack "jumps" (it's a clearly hearable xrun) every 0.5 seconds.... while it works fine in the normal kernel...
To you have any Ideas?
