[pulseaudio-discuss] [PATCH 06/23] Don't create nodes for monitor sources if the sink has ports

[Tanu Kaskinen]

The monitor source node should be created only if the sink has a node.
If the sink has ports, then a separate monitor node should be created
for each of the sink ports (will be implemented later).
