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

Last modified : Jun 27. 2018

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: 


●     Look for HDMI (ARC) port availability in TV.

●     Look for devices that feature Audio Return Channel functionality.

●     All HDMI cables higher than version 1.3 will support Audio Return Channel functionality.



ARC lets you direct the sound from the TV to the Soundbar or Home Theatre System speakers. It requires a HDMI connection and an Audio Return Channel (ARC) compatible TV. Follow these steps to setup audio (applicable for some models only):

To Connect A Soundbar:Click to Expand
1 With the Soundbar and TV turned on, connect one end of the HDMI cable to the HDMI OUT (TV-ARC) on the bottom of the soundbar.
2 Connect the other end of the HDMI cable to the HDMI IN (ARC) port on your TV (or One Connect box).
3 TV ARC will appear in the display window of the Soundbar main unit and the TV's sound will be played.
4 If the TV's sound is inaudible, press the Source button on the right side of the Soundbar to switch to D.IN (Digital IN) mode.
To Connect a Home Theatre System:Click to Expand
1 Use an HDMI 1.4 cable to connect the unit to the TV.
2 Press the Home button and select the following sequence Settings > Audio > Audio Return Channel.
4 Set Audio Return Channel to Auto for the HTS to automatically determine if the TV and the other components are ARC compatible. When set to Auto, ARC and Optical Input will automatically be selected.
3 Set Audio Return Channel to On to enable the HTS speakers for audio output; at this time Optical Input will be disabled.

Please note:

●    When Anynet+ (HDMI-CEC) is Off, the Audio Return Channel function is not available.

●    An Audio Return Channel compatible HDMI cable must be used.
