No Sound from my ADS Instant HDTV PCI?!?

[AAAAAAAHHHHHHHHHHH]

I have no sound, and my ADS Instant HDTV PCI does not show up in Device Manager, so I can't update the driver software. Is there anyway to fix this, or am I never going to have any sound?

Try reseating the card.

Try it in a different slot if you have one.
