I have a receiver and an HD DVD Player, both are about eight years old. I recently tried to replace the HD Player with a Blu Ray Player. I though that the switch would be easy because the only thing connecting the HD Player to the Receiver was an HDMI Cable. So I just used the same HDMI cable and connected it to the new Blu Ray player thinking the connections would be the same. Now I can hear the new Blu Ray Player on the TV speakers, but not on the surround speakers. When I had the old HD DVD Player hooked up, the sound would go through the TV and/or the receiver. Would adding a digital audio cable to the receiver do it, or are there other suggestions?
