    Due to product specifications, your TV will automatically mute the Digital Audio (Optical) Out Jack when receiving Dolby Digital Plus audio. If you want to listen to Dolby Digital Plus audio, connect the HDMI ARC or HDMI eARC jacks on the TV to the output device using an HDMI cable.

    Note:  Your Audio System (output device) must support Dolby Digital Plus playback.
