In Dolby digital and all other modes there is no sound coming from the rear speakers. If I run the level test sound comes from the rear channels. The speakers are definitely correctly installed. The display says Dolby D. I've had the receiver for 4 years and it always worked. Is it "done "?
Broadcast TV is notorious for that. You'll probably only hear sound from the rear speakers during the sound track. If your receiver has an " all speaker stereo mode " switch to that when not watching shiny discs.
