play

Use the play command in the playback namespace to initiate group playback.

After a successful play command, if your app is subscribed to the playback namespace, it may first receive a playbackStatus event with PLAYBACK_STATE_BUFFERING before another event with PLAYBACK_STATE_PLAYING. Sonos players will buffer the audio ahead of time when possible, in order to provide the shortest time to play for the user, and to prevent any audio gaps between tracks.
