Why won't Apple Music stream to HomePod AND AirPort Extreme simultaneously via AirPlay?
I have multiple HomePods and an older AirPort Express (Firmware Version 7.8.1).
When I'm playing music with Apple Music I can decide to either play the music through my HomePods OR the AirPort Express (with HiFi boxes connected).
The issue is also described in the following post (some years ago):
Home App / HomePod / Airport Express - Apple Community
When I play to the HomePods I cannod add the music to the AirPort Express, since there's no checkbox. When I click on the AirPort Express the music stops on the HomePods and starts playing on the AirPort Express. The HomePods then become the ones without a checkbox to add the AirPlay streaming in the selection - and vice-versa (when clicking on HomePods the streaming stops on the AirPort Express and starts on the HomePods).
Why is this a limitation? Both HomePods and the AirPort Express are within the same network subnet...
