@Kuli, lies dir bitte Wie kann ich Musik hören, die auf meinem iPhone, iPad oder iPad Touch gespeichert ist? durch. Bei Fragen bitte nachfragen.

Lokale Musik aus der Musik App von iOS Geräten geht schon lange nicht mehr, seit durch Apple Updates Dinge verändert wurden. 

Maybe I don't see the problem, but here's what I understand. I am listening to an album on the iPhone. And then came Samba pa ti which I would like to listen on a Sonos player in my house or on all of them including the Samsung's. Then I just press Airdrop, see all my devices that are available, select the ones I want and finito. However, I may have missed the point.

That‘s a different thing… what you are talking about is using Apple AirPlay.

But choosing lokal music stored on an iOS decice directly within the Sonos app has worked some time ago and now isn‘t supported anymore.
