Enable system audio control
System audio control enables the TV remote control 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 component 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.
Enable system standby
The system standby feature causes other components to power off when you power off
your TV. Depending on the CEC System Standby implementation, it also might enable
connected components to power off your TV when you power off the component.
System standby is disabled by default. To enable system standby, in the Home screen
menu, navigate to Settings > System > Control other devices (CEC) and highlight System
standby. Press OK to enable or disable the feature.
