Paul, Just shifting the PCI IRQ should do no good at all. You would want to assign MULTIPLE PCI IRQs to get any benefit. You could assign multiple IRQs to PCI from the following list, as indicated from your output below - 3, 5, 7, 9, 10, 11. Why not try the following: ps2 pciirq 11 10 9 7 Then reboot, and pray that the BIOS and/or FreeBSD are kind enough to spread your devices across the available PCI IRQs. Since your sound is PCI I don't think there is a straight-forward way for you to assign it to an IRQ. Messing with PCI IRQs should just be an exceptional case to get around poor (or overloaded?) device drivers.
