When audio playback is discussed, the receiving end is a server.

In theory, yes.

On the sender, install PulseAudio and load several instances of 
module-tunnel-sink (or module-tunnel-sink-new), and one 
module-combine-sink. Please use "pacmd describe-module" and "pactl list 
short sinks" to figure out the correct module arguments.

The caveat is that I recently got a private email from ValdikSS that 
tunnels don't really work with mpv (playback stops after a few minutes), 
even with pcaps attached. I have not debugged this.
