If the A/V receiver does not recognize a surround sound signal (the display reflects 2-channels only), or if the Dolby® Digital icon does not light, follow the steps below to troubleshoot this issue.

IMPORTANT: For information about configuring the digital source to output a Dolby Digital signal or if model-specific information is required to complete any of the steps in this solution, check the specifications or supplied operations guide. Manuals are posted on your model support page.

  1. Ensure the digital source is set up to output a digital signal.
  2. Ensure that the A/V receiver is set to either Auto Format Direct (A.F.D), Dolby Digital, or DTS.
  3. Ensure the A/V receiver is set to the appropriate input to receive the audio from the digital source.

NOTE: After completing the steps above, and the A/V receiver is still not recognizing the surround sound signal, perform the steps found in the A/V receiver manual for Initializing the setup operations. Initializing the A/V receiver, however, will do a complete reset and will return any settings you have made back to their factory defaults.
