If you have a HomePod and picked up the new Apple TV 4K, your speaker will make for a better home theater companion than it did before. As noticed by MacRumors, the latest Apple TV 4K supports the ARC (Audio Return Channel) and eARC (enhanced ARC) standards over HDMI. What this means in practice is that the Apple TV 4K can wirelessly send all audio from your television to a HomePod (or stereo pair of HomePod speakers).
