'Twas brillig, and Nikos Chantziaras at 24/06/10 16:17 did gyre and gimble:

As the hover over suggests, the "Input Devices" tab only lets you select
a "fallback" device. Ticking the box doesn't actually change things.

You need to go to the "Recording" tab where you will see the application
currently recording. Next to it you should see a little button that lets
you change the device that is in use for that specific application.

Changing this will move your stream and remember it for later.

Also, what do you mean the "input monitor"? A monitor source, by it's
very definition, is only going to monitor a sink. If in doubt paste a
link to a screen shot or two and I'll try and explain better.

I don't think this is a bug, it's just a conceptual misunderstanding.
