Until you have pavucontrol fixed there is a command line approach. I
think this should work:
$ pacmd list-sources
... find out the number N for your webcam (look for "index" at the
start of a section mentioning its type, or do something like:
$ pacmd list-sources|grep -E "device.product.name|index"

$ pacmd set-default-source N


To move a particular one (e.g. skype) once already started,
$ pacmd list-source-outputs
... find the number M for skype.
Or something like:
$ pacmd list-source-outputs|grep -E "index|application.name"

$ pacmd move-source-output M N
... should move only skype (output M) to the microphone (source N)


I've reconstructed this from what you'd do for sources, for which the
equivalents would be:
list sinks
set-default-sink
list-sink-inputs
move-sink-input
