I'm planning out a whole-house audio setup and considering AirPlay 2 against Sonos, Squeezebox server with Raspberry Pi's, etc. But I'm still unable to find out specifics about the multi-room capabilities of AirPlay 2. I'm wondering if Airplay 2 can do the following (I realize I need the appropriate hardware for this, I'm just concerned about the software/control capabilities): 1) Stream different music to different rooms at the same time. For example, can it play reggae on the back patio and easy listening upstairs where my wife is working, all controllable from my iphone? 2) Can it sync the audio to different rooms? For example, can I play reggae on the back patio, and select the kitchen as well, and have it play in sync so walking from the kitchen to outside does not change the music? Thanks for any answers..
