HDMIARC

HDMI ARC stands for High-Definition Multimedia Interface Audio Return Channel. It is a feature integrated into the HDMI specification that allows an audio signal to travel from the television back to an AV receiver or soundbar. Traditionally, HDMI connections were used to send audio and video signals from a source device, such as a Blu-ray player or gaming console, to a display. However, with ARC, the need for a separate audio cable is eliminated for certain audio sources.

When ARC is enabled, a single HDMI cable can carry both video and audio signals. For example, if you are watching content from your TV's built-in apps, like Netflix or a streaming service, the audio from these apps would typically be sent directly to your TV's internal speakers. With ARC, this audio can be routed back through the HDMI cable to your connected soundbar or AV receiver, allowing you to enjoy better sound quality through external audio equipment.

To utilize HDMI ARC, both the television and the audio device must support the ARC feature, and they need to be connected via a compatible HDMI port, usually labeled as "ARC" or "HDMI (ARC)". It simplifies home theater setups by reducing cable clutter and streamlining audio output from the television to external sound systems. Not all HDMI ports support ARC, so it is important to check the labeling on your devices.
