Using a batch file

[Nate]

Is it possible to use a batch file to change the default audio playback device?

I am wondering this because i have usb headphones that have their own soundcard and i use my speakers out of my actual soundcard.

What i want to be able to do is change which device is active. Normally i have everything coming through my headphones except my winamp which comes through my speakers. However sometimes i want to show someone something and so need to change the audio output to the speakers. I chop and change which way they are set many times per day and just wondered if there was a quicker way of doing it?

i guess this is some of it?
