Remarks
The TV's "Listen to:" setting may be set to SAP (analog program from
the ANT input).
• Check that DIGITAL AUDIO OUTPUT and/or AVR AUDIO
OUTPUT on TV's main panel is connected to the A/V receiver.
Without this connection, devices connected only to the TV (and
not the A/V receiver) can be heard only from the TV speakers.
Note that this includes the ANT input, a device (such as a
camcorder) connected to the convenience panel, and any other
device sending audio to the TV only.
• If using a NetCommand-controlled A/V receiver, NetCommand
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
Input Sensing and make the audio device selectable in the Activity
menu.
Disconnect headphones. Connect the TV's AUDIO OUT to the A/V
receiver and select AV Receiver from the New Device Found screen.
Remarks
• A/V Receiver Set Up for Audio-Only Switching
The A/V Receiver is not connected to any video input of the
TV. To check the A/V Receiver menu, temporarily plug into
an unused input of the TV, such as Input 3. Exit the New
Device Found screen and select Input 3 from the Activity
menu. Press MENU on the A/V receiver's remote control.
