It is known that many Sound blaster cards will share the parallel port IRQ without any indication in Windows. Although Soundblaster card's usually present little problems running in the same computer as Digidesign hardware, this IRQ arrangement may cause crashing problems on some systems. To disable:- Right-click MY COMPUTER, select PROPERTIES.- Select the DEVICE MANAGER tab, and look for Creative Misc. Devices. If found, double-click anything that says Legacy Emulation, and checkmark the Disable. Hit OK. If not found, check in your Sound, Video, and Game controllers for anything that says Legacy Emulation or Legacy Audio and disable.
