Greeting all. I am having a technical problem. It deals with a new Apple TV as well as my own incompetence. I recently bought the Apple TV and can't figure out how to hook it up to my system. We recently did a reno and had a home theatre put in where all the wiring is nicely hidden in the walls. I have a Denon AVR 2308 receiver and a Fujitsu plasma screen. The speakers are B&W. There are no speakers on the TV. I can get a picture from the Apple TV but no sound. The video hookup from the receiver to the tv is not with a HDMI cable. I can get a video signal by running a hdmi cable from the tv directly to the apple tv. I have an optical cord but can't figure out where to put it. There is an outlet on the back for DVR and I plugged the optical cable through it to the apple TV. When the receiver is tuned to DVR there is no sound. I would have thought there would have been. Does anyone have any suggestions? Thanks in advance.
