IRQ problem betweem sound card and IDE controller

You can specify IRQ's and DMA's in BIOS but there should not be a need to do so. What you could try is uninstall and remove the soundcard, then place it in a different PCI slot. If this does not work go to your BIOS and see if "pnp OS installed" is set to no, this setting allows BIOS to configure all your PCI pnp hardware like the soundcard and should set an IRQ for it that does not conflict with other hardware.
