Enabling 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.
•
A CEC-‐compatible amplifier 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 TCL• Roku TV speakers
” on page
62
) and resumes local
control of volume and mute state.
