ARC (Audio Return Channel)

Audio Return Channel (ARC) is a feature of HDMI connections that allows audio to be sent both ways through a single cable between a TV and an audio device like a soundbar or AV receiver. This means you can easily listen to TV sound through your external audio system without needing a separate cable for audio output. Essentially, ARC simplifies your setup by combining video and audio signals into one cable, reducing clutter, and making it easier to enjoy high-quality sound from your TV's apps or broadcasts on your external audio system.
