Gigabyte Gaming 5 z170 Audio setup

[Tesseract]

Hi, I am trying to set up my PC to output audio through the motherboard into a 7.1 channel receiver. I have an r9 380 graphics card that I output directly to my display. I am trying to get 7.1 surround sound to my receiver without running my graphics card HDMI through my receiver, since doing so causes resolution detection issues. Is there a way to get my audio out to my receiver without running an HDMI from my graphics card, to my receiver, and then to my monitor? I want graphics and audio to be through separate cables. Could the motherboard HDMI port output only audio? Or should I put the optical jack and a rear speaker aux cord out to my receiver?

Also please let me know if this belongs in a different thread, specifically for audio.

You do have a audio out on the MB. If you receiver has digital in put. Get yourself a digital cable and connect it. The other thing you can try is get a Y connect that you can plug into the the computer and you can plug into the receiver.
