I thought I had AVR300 + DV79 all going so well but made a couple of errors. 1. used Rainbow 5 from wireworld to connect all DVD-A outputs / inputs - even though I have no DVDA to play - thought I'd be ready for the future but all I did was confuse the issues! 2. assumed that (following excellent advice from Barend) that the low volume on CD was due to sensitivity setting - changed that but also removed L and R from DVDA inputs to CD inputs - increased volume due to this change rather than sensitivity change. Should know at my age to change only one variable at a time! Problem: to hear surround sound when using my Infocus 7205 I have to use DVDA input setting on AVR300. I am getting no sound through the coax connection. The onscreen three-second display states that the audio input to the DVD port is analogue not digital. Possible answers??? Coax from DV79 not delivering digital sound or Cable malfunction or inout to AVR300 malfunction. Changed cable - still no sound. Purchased optical cable - digital sound transmitted but have to use different input (PVR) to DVD and not re-assignable. Summary can watch DVD and get surround sound if I use the DVDA analogue inputs but if I want to listen to stereo CD I have to unplug front L and R and put them in CD inputs. cannot get anything through the coax - AVR says that an analogue signal is coming through Optical connection works but there is no optical DVD input even though there is an optical output from the DV79 Can anybody help? Am I missing something really simple and dumb or is the coax output (DV79) or input (AVR300) just not functioning?; I've read the manuals and scoured the set-up menus. I've got a couple of other problems too - but would like to solve this first.
