Mumble always specifies device explicitly when connecting a stream, even when "Default sink" / "Default source" is selected.
And these devices in mumble are not updated when the default source/sink is changed in PulseAudio, because mumble does not subscribe to PA_SUBSCRIPTION_EVENT_SERVER.

Suggest either
1) pa_context_connect_record should specify null as its dev parameter when the "default source" option is selected. This would also make the stream movable, so if the default source is changed while a stream is running, it will be moved automatically.

2) at least subscribe to updates of default source and sink, so that the next time pulseaudio engine is restarted (is that when the audio wizard is opened?) the correct device will be used?

It doesn't seem to work quite as we might expect. It seems to stay on the USB mic in all cases when on Default.

It looks like the sound settings UI does not move inputs correctly, so I've filed bug 984637 for that.
