Also see the "Sound" section in this file! On Windows the SDL sound backend

I've build Yamagi Quake II with SDL 2.0 and now my mouse behaves strange.
- If it feels like your mouse is hitting the window borders you're
experiencing a problem in SDL 2.0. SDL 2.0 needs XInput 2.2 or higher
and fails when the installed version is older. So make sure that you
have XInput 2.2 or higher installed.
