[PlanetCCRMA] problems with jack ?

i am short with my time, so it always takes some time to answer (but
thanks for your fast replies). and this is, what i found out since my
last mail:
i did disable acpi - nothing changed.
i did disable usb - nothing changed.
and i did try to disable everything i do not need, but that did not help
either.
what i did not try yet is marks fluxbox-idea - i will try, when i find
the time...
but one thing makes all that strange to me:
if i do not use jack, i do not have this problems. if it would be
another process, that is running, or if it would be an hardware-conflict
- why does it only happen with jack ?
perhaps that information gives someone a new idea for helping me ;-)
(if not i will try the fluxbox-idea)
thanks and greetings - olaf
