Is there a way in Windows XP to change left and right channels in sound output?

Unfortunately, there is no way to do this using Windows controls. Some sound cards might have a reverse-stereo configuration, but that wouldn’t be a function of Windows.

You can’t move the speakers, but you can reverse the channels in line. This is kind of a Rube Goldberg solution, but bear with me:

Get this and this. Plug the red jack on one into the white jack on the other and vice versa,, then plug your speakers into the line, and you have reverse stereo. if this is a laptop with built-in speakers, never mind.

That will work, thanks
