That's what it appears but it still seems to pick the default for the
thing you don't specify...

e.g. if you only give a source, then it will also use the default sink.
and vice versa.

You can tell it not to do that with this:

ctl.sink5 {
    type pulse
    sink "5"
    source "-1"
}

but the source still shows up but manages to some kind of dummy thing.

I guess the plugin code could be tweaked to not have the control if -1
is passed?
