Hi,
I have an older Denon AVR 682. It's a fantastic little receiver, but it won't switch to Dolby Digital any more. It's done this once before, but I can't remember what I did to get it back. The owner's manual does not say how to switch it, it's supposed to do it automatically. I can switch ProLogic, cinema, etc. I'm at my witt's end. Anyone know what I can do to get Dolby Digital back? Thanks in advance.
