left menu. Highlight the Dolby Digital tab and press SELECT, then follow the onscreen instructions and
select from the following options:
On: Turns on Dolby Digital audio output. (Note: True Dolby Digital is only available via HDMI or
optical outputs.
Off: Select this option to turn off Dolby Digital Audio output.
