Apologies if this is obvious, but I've searched a lot and can't find a definitive answer.
Does Airplay 2 send all audio to an enabled Airplay 2 speaker, or just audio from certain apps? e.g. is it like Bluetooth that will replace the internal device speaker with the bluetooth speaker, or more like Chromecast that will only work with some music apps? If the latter, is there a list of which apps work with it - e.g. Safari? Facetime? Or is it just the IoS Music App? Thanks for help.
