Your hardware description is too vague for us to help you. Please provide the following information:

1: Is this from a desktop or laptop pc?
2: Is the device stand-alone/add-on or is it integrated on the motherboard or is does it plug into a pci slot as you indicated.
3: Brand and model of pc it came installed in or brand and model of motherboard it came pre-installed in.

You must give us something to work with because as it stands we cannot help.

and btw, Trident never made any sound chipsets that I'm aware of. The made VIDEO chipsets.
