Saving default audio device in Vista

You guys with Windows Vista, How do you get your default audio device to stick? Every time I set my default audio device to my Realtek High Definition Audio, hit OK, then restart, it defaults back to USB Audio Device which is my magicJack. Which means I have no sound from my desktop speakers until I set the default back to my Realtek High Definition Audio Device. Do I really have to do this every time I restart my PC? Is there a way to get it to permanently save the defaults I selected? I have used magicJack for over a year with Windows XP and never ran into a problem like this.
