I have a surround sound system that is connected to my LG Smart TV via Optical. The TV is connected to my HD 7790 via HDMI.
The problem is that I only get the "Stereo" option via in Playback Device Configuration (Windows 7 x64).
I understand that this is most likely due to my TVs EDID. I need to force it to 5.1 from the current stereo mode (kind of like you do from the Sony Playstation). How can I do that?
