Sharp TV Digital Setup

[avskier]

My Sharp TV model LC-52D64U displays only "Software Update" in the "Digital Setup" menu option. I need to set the Audio to "PCM" only for my digital headphones. I performed a manual firmware upgrade but it made no difference. Any help would kindly be appreciated.

as per your manual, the digital setup is NOT available for hdmi / pc inputs.
