I currently run a Gigabyte GTX 260 (GV N26OC-896I) and an Asus P7P55D-e Pro.
I am using the on board audio driver (VIA) and have a S/PDIF cable going from my motherboard to my graphics card.
I have a HDMI cable going from my graphics card to my amp, which has audio/video pass through for HDMI.
I can get 2.1 channel, but not 5.1 channel.
Has anybody got any solutions?
