Hi Eric, I think you need an AC97 codec mounted on a motherboard in order to run this sample driver directly. All new motherboards are now HD Audio, so they won't work either. You'll need to find an old motherboard which has AC97 on it. The creative card is a PCI device, and uses a proprietary chipset, so this sample driver will not work with it.
