Hi all. I'm looking for the best possible audio connection between my desktop PC and my Denon AVR-S920W. The receiver is 7.2 and I want to be able to utilize all 7 channels. Also, I do have a USB DAC, the Mayflower Objective O2 Headphone amp, but I'm not sure if I'll be able to run it with surround as there is only 2 channels. I have my PC connected to monitor via DisplayPort for video, and USB DAC for audio.
I did some research and it looks like my options are:
1. HDMI Out from GTX 980 gpu to HDMI in receiver
2. 3.5mm Out from DAC to RCA analog in receiver
3. 3.5mm Line/Headphone Out from motherboard to RCA analog in receiver
4. Optical TOSlink Out from motherboard to Optical TOSlink in receiver
Which of these will be able to utilize the full potential of a 7.2 setup without interfering with the DisplayPort video? Some have recommended HDMI, but I'm afraid it will interfere with the video and try to bring it to the HDMI of the TV.
