Just wondering if anyone has any idea for getting 5.1 audio from the pc to my denon reciever via digital coax. I currently have a SoundBlaster Audigy 2. It states on the back of the box that you simply need to use a mono minijack, which is what fits into the digital out on the pci soundcard, to RCA 3.5mm cable(and I assume into the digital coax input on the receiver). However, this would not seem to make sense. Is a digital coaxial cable for audio just simply the same makeup as a standard RCA cable? Can someone offer a suggestion on what exactly I need to get to make this work?
