This is driving me nuts. I recently moved the family computer from the basement into the dining room. This was done so that we could better monitor our 13 you son's computer usage. The problem is we want to be able to easily switch between the speakers and the headphones. The existing speakers do have a manual volume control knob. At this point I have to get down in back of the pc and swap out the plug for the speakers or the headphones. I would like to be able to use both without having to swap out the plugs. Any ideas? Thanks in advance.
