I have my reciever connected to my pc through one of my 980s hdmi port, and this causes my pc to look at it as a screen. when i turn sli on, that screen turns gray in controlpanel and wont activate, so i get no sound. I tried connecting my reciever to my mobos hdmi, but it doesnt show up in playback devices, so that doesnt work. What id like is for my pc to see my reciever as speakers and not a screen, but i cant find out how to do it, i dont even know if its possible.
