Using a null sink and its monitor is the only way that I know to do application-to-application routing. R?mi'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. -- Tanu
