and I dont understand two things:

Hello Fero,
Where did you get the realTimeConfigQuickScan script? The author updated
it a month ago so it also checks for the right CONFIG option for 3.x
kernels. And did you compile the kernel yourself?
and the second, how to:
** Set $SOUND_CARD_IRQ to the IRQ of your soundcard to enable more checks.
Find your sound card's IRQ by looking at '/proc/interrupts' and lspci.
??
This only applies for onboard or PCI audio interfaces, so not for USB
and FireWire interfaces.
Regards,
Jeremy
