Why ARC/eARC is important for the home theater setup?

ARC (audio return channel)

It allows a single HDMI connection to be used as both an input and an output, which eliminates the need to use a dedicated audio cable to connect a soundbar or AV receiver to your TV.

HDMI ARC can provide a two-way flow of audio between your TV and audio system via just an HDMI cable. It can be one of the best home theater features, as it can reduce cable clutter, save more cost and simplify your home theater setup.

eARC (enhanced audio return channel)

EARC made some improvements on ARC, able to stream more complex multichannel formats, like Dolby TrueHD and DTS:X.
