DIGITAL AUDIO OUTPUT and/or AVR/SURROUND

Note that this includes the ANT input, a device (such as a
camcorder) connected to the TV, and any other device sending
audio to the TV only.

may be selecting the wrong A/V receiver audio input. Check the
A/V receiver's NetCommand setup in the Inputs > AVR menu.
Plug an unused video plug into the Y/VIDEO jack to activate Auto
