Problem connecting optical connection

What device are you attempting to connect to your receiver? I would check to see if the device you want to connect is sending a digital signal to your receiver. With some dvd players the digital output isn't activated. You will have to go into the menu of the dvd player by using the remote and pressing menu or setup. Find something that involves audio, this setting maybe it PCM or Bitstream. If it is in PCM you will need to change it to bitstream to receive the Dolby Digital sound.

Also you may wish to check what mode the receiver is in. You may have to tell the receiver that you are using a digital input versus an analog one. Your owners manual may be useful with this step.

Let me know how it goes.
