Got mine today and as it supports HDMI 2.1 I've connected it straight to my LG G1 with audio going via ARC to receiver (not eARC).
Doing this before on the previous gen ATV 4K resulted in lip sync issues with Dolby Atmos on ALL apps and iTunes movies too, connecting straight to AVR was fine and that's how I used it.
Now the new one connected straight to tv has no lip sync probs with Atmos apart from Netflix, it's slightly out.
