HDMI Connection (ARC/eARC)
Connecting the television and audio system with an HDMI cable. This is the recommended method of connecting an external audio device.
Use an HDMI cable to link the HDMI input terminal on the television marked with "ARC" or "eARC" to the HDMI input on the external audio device bearing the "ARC" or "eARC" text.

(B) HDMI cable (not supplied)*
Note:
To ensure proper operation of the eARC function, use an HDMI cable labeled "HDMI High Speed with Ethernet" or better.
Additional settings for HDMI ARC connection
For this connection to work, HDMI CEC must be enabled on the TV. To do this, press XXX.GST (Settings) button, then select [All settings] > [General settings], scroll down and activate [CEC]. If you want to control the volume of the connected device using the TV remote control, enable [CEC remote control] in the same menu.
If your connected audio system is not producing sound, it is possible that it does not support the required codecs. In such cases, you can try allowing the TV to decode the sound. Press the XXX.GST (Settings) button and select [All settings] > [Sound] > [Advanced] > [Digital out format] > [STEREO (uncompressed)].
Differences between ARC and eARC explained
If your external audio system only supports the HDMI ARC function, the TV will only be able to transmit compressed audio with a maximum of 5.1 channels.
If your external audio system supports the HDMI eARC function, the TV will be able to transmit uncompressed audio with a maximum of 7.1 channels. Transmission of object sound, such as Dolby Atmos and DTS:X, is also supported.
