How do I use ARC (Audio Return Channel) port in my Smart TV?

Samsung TVs support ARC (Audio Return Channel) function via HDMI cable. ARC enables the output of digital sound using just an HDMI cable. However, ARC is only available through an HDMI (ARC) port and only when the TV is connected to an ARC-enabled AV receiver. Connect an HDMI cable to the TV's HDMI (ARC) port and the device's HDMI output connector.

HDMI ARC sends down audio signals back to the connected audio device that is syncronised with the picture and there is no need of having another audio cable. 

Following ensures Audio Return Channel functionality in your Samsung TV:
