Running two paired HomePods to Apple TV. No lag at all with sound. Very very happy. Quality sound now when watching content via Apple TV and great sound / volume too. AirPlay 2 and iOS 11.4 making this all work quite well now. Funny how Apple doesn't yet market HomePod as a wireless speaker solution for Apple TV as well as music etc... but any who, it works great...
Thanks. Just to clarify, the lag happens when you are streaming to a HP AND to speakers connected to an Apple TV.
I'm glad to hear that there is no lag when using 2 paired HPs for audio output with Apple TV.
How about when people stream to 2 UNPAIRED HPs. Is there any lag?
