Which binding has the "best" implementation of Audiosink?

[BeanzBE (Lennert Coopman)]

I would like to add Audiosink functionality to the Yamaha Musiccast binding. There are bindings which have implemented this and I started looking at some of them: Sonos, Onkyo, PulseAudio, Chromecast, …
It seems like all of them have a different implementation.
Which one of them can I use as example to start testing and building? Thanks.

There is a Yamaha Receiver Binding. Wouldn’t it make sense to look into that one first?

I looked at that Binding but that one does not support Yamaha Musiccast and I don’t see any reference to audio streaming. I might be wrong so still appreciating any tips or tutorials.

Did some coding today based on above mentioned bindings. All compiles but no sound is coming through…
