**HDMI ARC (Audio Return Channel) Port: What It Is and How It Works**

An HDMI ARC port, or Audio Return Channel port, is a type of HDMI port that allows an audio signal to be sent back to the source device through the same HDMI cable that is used to send video and audio signals to the display device. This means that you can connect your TV to an audio receiver or soundbar using a single HDMI cable, and the audio receiver or soundbar will be able to send audio back to the TV, eliminating the need for a separate audio cable.

HDMI ARC is supported on all HDMI 1.4 and later ports, and it is indicated by the ARC logo on the port. To use HDMI ARC, you will need an HDMI cable that is certified to support HDMI ARC.

Here is a more detailed explanation of how HDMI ARC works:

1. When you connect an HDMI cable from your TV to an audio receiver or soundbar, the TV will send an audio signal to the audio receiver or soundbar through the HDMI cable.
2. The audio receiver or soundbar will then play the audio signal through its speakers.
3. If the audio receiver or soundbar supports HDMI ARC, it will also send an audio signal back to the TV through the HDMI cable.
4. The TV will then play the audio signal through its speakers, or through external speakers that are connected to the TV.

HDMI ARC can be used to send any type of audio signal, including Dolby Digital, DTS, and LPCM. It can also be used to send high-definition audio signals, such as Dolby TrueHD and DTS-HD Master Audio.

HDMI ARC is a convenient way to connect your TV to an audio receiver or soundbar using a single HDMI cable. It is supported on all HDMI 1.4 and later ports, and it is indicated by the ARC logo on the port.
