Digital audio out with Vista?

[btcomm]

There is no custom tab. When I go to properties on the speaker icon it has general, levels and advanced. If I go to the built in sound card it has an enhancements tab added to that, no where do I see enable digital IO.

This is on the card that had digital audio in windows 98, I took it out and put it in this new vista machine.

I tried installing a audigy SE card and installed the drivers for that again and there is supported formats tab. When I try that I try DTS audio and Dolby digital, if I test either one of those I get bad sounding static out of the speakers. If I test the speakers after that I still get no sound at all. What gives?
