If the Dolby Digital / DTS indicator on your Pioneer Receiver doesn't light up even when playing a Dolby Digital / DTS source, ensure the source is playing and not paused or stopped. Check the audio output settings on your player, referring to its manual. Also, the current track may not be in Dolby Digital / DTS format.
