I'm looking for a simple volume controller to keep on my desk that I can plug into a soundcard and go to a set of headphones. It seems like the only thing related that I can find are external sound cards or MIDI interfaces and all I want is a device that simply controls volume for whatever is plugged into it. Surprisingly, I'm having kind of a hard time finding one. Can anyone help?
EDIT: Clode thread. I found this.
