I have just got a coxial digital lead and have connected it up to my Sony BD930 amp (Creative Audidgy 2, digital out)). I can get 2.1 sound but not 5.1 When it is set at 48Khz there is the 5 speakers shown on my amp but no sound from rears or centre. When I have it set at 96Khz there is only 2 speakers shown on my amp and I still get 2.1 sound (better quality than 48Khz) but still no 5.1 I have a £50 pro lead (coax) with a mono 3.5mm to phono connector. Do I need a stereo connector instead? Or am I missing something else? Any help would be appreciated.
