1.) if the IRQ-script shall work, you must have your soundcard set
excluselively to an IRQ by using the BIOS-Setup, especially, if your
Sounddevice shares an IRQ with an active Harddrive, you will get xruns
even if you let Paul Davis himself set up you software for RT ;-)
I'm on an IBM T41 laptop, questions:
1) It seems my IRQ's are suboptimal:

How do I change the IRQ of my sound card (Intel 82801DB-ICH4)? In the
bios? I suffer from bios-fobia, so if "yes" anyone knows if it's
possible on a T41 and if so could give a quick help?
2) If not possible, what would be the next-best solution?
3) I also have an usb soundcard. If possible should usb be put on a
seperate IRQ also for this to perform the best?
