I have two GTX 980 in my PC with one HDMI port per card so I decided to try and see if it would not only output video from my main card to my TV but also bitstream and output audio from the second card without issues and it worked 100%. I just plug it in as normal and the system didn't even have flinch it just played it seamlessly through both cards. GPU #1 is outputting to my TV and GPU #2 is bitstreaming audio to my AVR and everything is in sync and alright. Below are two photos, one of the back of my PC and the other the Nvidia control panel. also Sli is disabled and i didn't try of it worked with it enabled.
FYI, passing video through your AVR or not does not impact / change image quality. It either works or it doesn't. You should just go back to hooking up to your AVR as you lose HUD on volume changes and the ability to make changes on your AVR menus and you gain nothing.
