I've seen a couple of PC switches that let you hook up two audio plugs into it (ideally, the headphones and speaker), and let you toggle between the two with the push of a button. It seems easy and affordable.
The thing is, I could really use a similar device that lets me hook up three audio plugs to it, the third being the audio plug from my TV whenever I hook up my PC to it. Does such a device exist, or does it only come in two outputs? Please help me out.
