I have my Video coming out from my PC to my SUHD TV with and HDMI cable. I have a Fiber Optic(for audio) from my SUHD TV to my Surround Sound. The HDMI cable coming from my Computer to my TV is what carries the Audio as well but it's only showing an option to setup for Stereo and nothing else i.e. Surround 5.1 , 7.1, etc. Is there something I am not doing to create a surround sound output from my graphics card to my tv? I have my TV on and on the correct input(PC and the correct HDMI for it) I can hear the computer sound and all but it doesn't show or "test sounds" as a 5.1. only Stero (left and right speaker).
