Hi, I just built a brand new computer with the Sound Blaster Audigy Platium 2 ZS sound card, so now I want to know how to hook it up to my receiver. My receiver have 5.1 inputs for DVD-Audio and digital inputs, but I can't seem to get 5.1 out of the sound card's digital outputs(I only get front left and right out of the front panel input). The speaker settings on the sound card is 5.1, but it doesn't seem to do anything. Any advice would be much appreciated.
