Thanks bang1. I'll look into the default options soon.
In the mean time I have received my SPDIF card for my PC and hooked up a digital coxial cable. I've connect the two L&R RCA s and the digital coaxial to A1. I've also selected this the A1 as the sound input for my PC in the connections tab in the menu. BUT it doesn't work! I get no sound when playing a 5.1 encoded video file. The sound does come through the analogue ports though...
Got very frustrated and gave up late last night. Will do some more experimenting this weekend. Any suggestions as to what I'm doing wrong?
