You can verify what streams are connected to what devices with "pactl list", and prevent unwanted source output moves from happening by giving parameter "source_dont_move=true" to module-loopback ("sink_dont_move" exists too, which will prevent the sink input from moving from the initial sink to somewhere else). -- Tanu
