Hi guys, just moved my main computer from upstairs to hook it up to the tosh 37" in my lounge and hooked it up to my pioneer home cinema set-up. I'm using the onboard spdif output on the my asus mobo, and have connected it to the same socket that my xbox 360 was plugged into on the pioneer using the same cable, so i know the cable and connection work. But i seem to only be able to get 2 channels working, the front 2. I've had a poke around in the realtek software, and it shows that spdif is an option, but just can't see if i can enable it anywhere. Any help?
