S/PDIF output
The S/PDIF outputs, optical and coax, will follow the main TV and output audio only when the current audio
format is compatible with S/PDIF.
Audio Return Channel (ARC)
In some setups, it is desirable to use the TV as the source of audio. This is most common when watching
live terrestrial TV from an HD antenna. In this case, the TV is receiving a live ATSC signal over-the-air. The
video is shown on screen, but the user would like the audio to be played from the AVR (red path).
In most cases, the preference is for audio to be routed from the Matrix

HDMI or MHL inputs to the Aux
HDMI output or to the S/PDIF output, and ARC is only used when viewing over-the-air broadcasts.
Most TVs can be put into Automatic ARC mode so that when they sense that an audio receiver capable of
receiving ARC is connected they automatically negotiate with the receiver to establish an ARC channel.
