I need a sound card that will work with Vista 64 bit and will allow digital passthrough either via s/pdif or toslink. Can someone reccomend a card that will do this for under $50? I have one now that works great except for the fact that the drivers I need to use aren't digitally signed, which is a problem for Vista 64 bit... I have to press F8 everytime I boot to disable digial driver enforcement, and that gets old really fast. My current card is a Diamond XS71 in case anyone cares.
