[pulseaudio-discuss] How is "pa_sink_input_process_msg" called?

Great thank, Tanu!

So "protocol-native.c" is a implementor for a sink input, right? It has a "sink_input_process_msg" which overrides the default message handler as you said.

I have another question: is it possible for a sink input connected to multiple sinks? If yes, in which thread is the message handler is called? 

Thanks
