[pulseaudio-discuss] [PATCH 5/9] source: Initialize pa_source.monitor_of already in pa_source_new()

[Tanu Kaskinen]

The knowledge about whether the source is going to be a monitor source
is necessary already in pa_source_new(), because the monitor source
node will be created based on that information.
