[PlanetCCRMA] problems with jack ?

thanks to mark and the others for helping ! i am still working on the
first suggestion (other programs that run), but i already tried on
hardware side, because mark was not the only one who said that and now i
want to report:
i disabled all usb in bios (just for testing) and as far as i could see,
it really was disabled (cat /proc/interrupts did not show usb and
according to that, ice1712 has its own interrupt). but my jack-dropouts
are still there...
this as an info for you
greetings - olaf
