I have a biostar g41-m7 mother board a nvidia geforce 9600 gt video card on board audio and a yamaha rx-v473 5.1 receiver. I want to send video and 5.1 audio through the dvi on the video card to hdmi to the receiver. The mother board does not have SPDIF on it however the video card can accept SPDIF I need a cheap low profile sound card with SPDIF out on it or another way to connect all of this to my receiver
