Enable system audio control
System audio control enables the TV remote to change the volume and mute state of
an amplifier or sound bar connected through HDMI
®
, and to display the external
device’s volume and mute status in the TV’s on-screen display.
The TV automatically turns off its internal speakers and sends volume and mute
control signals to an external amplifier when all of the following are true:
• System audio control is enabled on the TV.
• The TV is connected to a CEC-compatible amplifier, it is powered on, and CEC
discoverability is enabled.
• The CEC-compatible amplifier’s HDMI
®
ARC connector is connected to the TV’s
HDMI ARC connector with a suitable HDMI
®
cable.
When the CEC-compatible amplifier is off, the TV automatically turns on its speakers
(unless you have turned them off as described in Turning off the speakers
) and
resumes local control of volume and mute state.
To enable or disable system audio control, in the Home screen menu, navigate to
Settings > System > Control other devices (CEC) and highlight System audio
control. Press OK to enable or disable the feature.
Enable 1-touch play
1-touch play enables a device to control which TV input is active. For example,
pressing Play on your Blu-ray™ player switches the TV to the Blu-ray™ input.
1-touch play is disabled by default. To enable 1-touch play, in the Home screen menu,
navigate to Settings > System > Control other devices (CEC) and highlight 1-touch
play. Press OK to enable or disable the feature.
