Enabling system audio control
System audio control enables your Sharp Roku 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 your Sharp Roku TV’s
on-screen display.
Your Sharp Roku 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 your Sharp Roku TV.
• A CEC-compatible amplifier is powered on and CEC discoverability is enabled.
• The CEC-compatible amplifier's HDMI ARC connector is connected to your Sharp Roku TV’s HDMI ARC connector with a
suitable HDMI cable.
When the CEC-compatible amplifier is off, your Sharp Roku TV automatically turns on its speakers (unless you have turned
them off as described in
Turning off your Sharp Roku TV speakers
on page
) and resumes local control of volume and
mute state.
System audio control is disabled by default. To enable system audio control, in the
Home
screen menu, navigate to
Settings
> Control other devices (CEC)

. Press
OK

Enabling 1-touch play

Home
screen menu, navigate to

more seconds. When the restart operation is complete, you’ll see the familiar
