I don't really get what's so exciting about Airplay 2. Could someone explain it to me? I have a couple Sonos products and I've noticed a lot of Sonos owners are excited for it too. Don't see how it'll operate any differently with Airplay 2 than it currently does
It'll mean you won't have to use the Sonos app, for one. You can use the native Music app and just select it as a source as you would AirPods or any other Bluetooth device. Also, if you have a HomePod (I have a mixture of HomePod/Sonos speakers), you can choose both HomePod and Sonos speakers to play to, again directly from the Music app.
Assuming this will also somehow apply to Siri (on HomePod) - asking her to play a song on multiple speakers.
Having said that, this will unfortunately depend on what Sonos device/s you have. Sonos have confirmed that it's not coming to all of their products, I believe only the Play:5 and One?
