Tell Siri Where to Play Your Videos and Music
If you have other AirPlay 2 devices in your home, such as Apple’s HomePod, you can now dictate to Siri where content should be played. This is usually much easier than wandering through menus to select alternate playback destinations, especially on the Apple TV.
To begin playing something back on multiple speakers, simply issue a command to Siri like:
Play YYZ by Rush in the living room and dining room
If you’ve already got a track playing on your Apple TV, you can instead ask Siri to “play this” in another room, like so:
“Play this in the kitchen”
This will add the room to the whatever is currently playing. If you want to instead switch to another room, tell Siri to “move this” or “transfer this”:
“Move this to the dining room“
This also works in the other direction. If you’ve got a HomePod, you can simply call out for Siri and tell it to start playing music on your Apple TV, either by naming the room it’s in or using the specific device name.
