If you don't use your COM/LPT ports you can disable them in the BIOS to free up some IRQs, maybe some cards will change from IRQ. Try to not let your soundcard share IRQ with another device, try different PCI slot configurations and look in the manual which slots share IRQ with eachother. The SBLive! can easily give problems when sharing an IRQ.
Another thing you might want to try is disabling the SB16 Emulation.
