Which is only used for new streams (existing streams are not automatically moved over). I have a small home-brew script which I use to switch the default sink AND move all current streams to that new default, but never figured out (didn't really try too hard) how to automate it to plugging in/out of audio equipment. I think it wasn't possible at that point in time to detect jack in or something like that.
