Until today, I was under the impression that I could only Airplay to devices that are enabled with this capability. In my case only my Amp is identified in my Sonos app as having this capability. None of my other older devices are identified as Airplay compatible.
However, this morning I was playing a programme from the BBC Sounds app and was streaming it via Airplay to my Amp, but to my surprise I heard the same programme being played through my other speakers in other rooms.
it seems that if, in Sonos, I select Amp plus other speakers, Airplay not only plays through the Amp but to theseother speakers as well.
Is this news to anyone else?
