Well guys I have connected my newly purchased AVR (Onkyo 807) to my PC using its sound card's optical out (x-fi xtreme gamer) but I could get only two channel sound (stereo sound) using that I Google about that and found this card is restricted up to stereo sound at max in optical out option.
So how can I get proper unprocessed 5.1 channel audio stream of my MKV files from my PC to AVR to do all the audio processing.
