Yes it’s possible, but both phones will mirror the GUI.
The first connected phone will be considered as “Master”
I am using a Andriod and iPhone.
I’ve connected the iPhone first , the android as 2nd.
If I select play here on the Andriod, the sound moves to the iPhone.
Does the Volumio app/interface allow you to play everything you doing on the safari? Let it be youtube, radio etc? Sorry if this is a already asked thing and or if i’m completely wrong. Asking because my wife listen to radio a lot and i need something easy for her
Web radio is available directly in Volumio without a plugin.
Thousands of web radio stations can be selected and saved as favorites. I use it like this and am very happy. It’s really very well done in Volumio!
