Ok I'll try and sort out a video.
If I say something like “hey google, broadcast this is a test message”
It'll say “ok, broadcasting now”
Then a couple of speakers might simultaneously play that recording, another a half second after, perhaps one after the others have finished,
They are no longer in sync.
So when it's a longer message, you have this situation where it's like people all over the house shouting at you and you can't understand any of it!
Never used to be like this.
Playing music to all speakers via the “home” group I created is perfectly sync’d
The solution is for the devices to do whatever they do for music, e.g. All listen for that bleep and sync up, then play the message.
