I have read that doing the 5,1 firmware hack enables the audio over HDMI/displayport, but I cannot seem to make this work. I currently have a 760 GTX card installed, and nothing shows up as far as audio from the card. Is there something else that needs to be done in order to enable this? I can't use HDMI since my monitor runs at 3440x1440 and HDMI won't support that at 60hz. Any help would be appreciated!
