Like on Macintosh (or even Windows, I suppose), iTunes will immediately recognize and use wireless streaming to play music via an Airplay device. I want my Ubuntu to do that. Simultaneous output, separate volume controls, play/pause, etc.
(BTW iTunes works fine, even the compact version from my iPad.)
I installed paprefs which gave Gnome a GUI, when installed with pulseaudio-module-raop, it adds a sound device, as advertised. But when I load my audio-player (tried many...) and play music, no sound is emitted when I select that device, although it will play fine on using the desktop-speakers - when selected. It never asked for the password. (I suspect this is why it doesn't work).
(I have tried many suggestions on ~oogle and all have failed.) Also I've tried many solutions (like airplay.jar, open-airplay, etc.) and they don't work with 18.04 and most are no longer maintained.
Hopefully there just an audio-player (like iTunes) for Ubuntu 18.04 that just plays to desktop-speakers as well as my home theatre.
Otherwise I can attempt to build from the code in say, open-airplay...
Ideas / suggestions... Has any Ubuntu users got a similar situation working - if so, how?
