When you go to the Control Panel -> Multimedia -> Playback -> Advanced Preferences -> Speaker Setup you can choose which kind of speaker setup you have.

I'm usually using quadrophonic speakers, but at late night I use headphones.

Is it possible to change the setup from VB, with some kind of registry related API perhaps? I have no idea that where the speaker setup info is saved, but I belive it is somewhere in the registry... It's just so boring to click so many times... :P

Alternatively I could do the thing by feeding mouse clicks and stuff but that's just an alternative.

Thanks.
