HDMI ARC and its successor, eARC, are designed to simplify audio connections from TVs to soundbars and home theater systems. Introduced with HDMI 1.4, ARC allows audio to be sent back through the HDMI cable, eliminating the need for separate optical audio cables. The enhanced version, eARC, which arrived with HDMI 2.1b, offers significantly more bandwidth to support uncompressed, high-bitrate audio formats like Dolby Atmos and DTS:X, providing a more immersive sound experience.
