I say possible because I can't fully test it as my motherboard audio device doesn't show up in Windows (don't know why yet). So, because of that and because this "fix" needs a little discussion amongst the troops, I've ifdef'd it with EXPERIMENTAL_HAVE_DEVICE_CHANGE and have disabled it by default. What is does is it sets up a device change listener and performs an automatic rescan when a change is detected. (That's the part that needs discussion.)
