Using a null sink and its monitor is the only way that I know to do
application-to-application routing. Rémi's idea about alsa's loopback
driver might work too, though - I have zero experience with that.

I think this workaround would work too: load module-virtual-source on
top of the monitor source of the null sink. module-virtual-source
doesn't do much itself (it just copies the data from the master sink),
but it shouldn't appear as a monitor source so your client can use it.
