The card should be recognized as a C-Media Audio Device in the control panel if the power plug is inserted. I note this, because the connector is known to be hit and miss for some people.

The sound card doesn't need the 4-pin floppy cable to work, but it does disable the onboard amplifier if there is no additional power. You get really low-volume sound out of the unit if the floppy cable is not plugged in. But the computer does recognize the card and such.

I believe you might need three drivers. The card itself uses the ASUS AV200 and the C-Media CMI8788 chips. The sound chips are actually a PCI interface and there is a PLX PEX8112 PCIe-to-PCI bridge chip to get them to work off a PCIe bus.

You might also try to make sure the PCIe slot is turned on in the BIOS since sometimes some OEM boards turn off slots that are not used as the machine comes from the factory.
