When ARC is active, TV does not mute its other audio
outputs automatically. So you need to decrease TV
volume to zero manually, if you want to hear audio
from connected audio device only (same as other
optical or co-axial digital audio outputs). If you want
to change connected device's volume level, you
should select that device from the source list. In that
case volume control keys are directed to connected
audio device.
System Audio Control
Allows an Audio Amplifier/Receiver to be used with
the TV. The volume can be controlled using the
remote control of the TV. To activate this feature set
the Speakers option in the System>Settings>More
menu as Amplifier. The TV speakers will be muted
and the sound of the watched source will be provided
from the connected sound system.
Note: The audio device should support System Audio Control
feature and CEC option should be set as Enabled.
