I want to set up a home audio system with speakers throughout the house. Here's my problem: I would also like to be able to run the audio from my tv, xbox, Stereo system, Computer, Ipod, and other audio devices all on the same system without having to unplug and plug in devices every time I want to use something else. Of course I am not trying to have them all playing at the same time, so I need something that will allow me to have them all plugged in and switch between them as I need them. I'm not sure what kind of device to use. And Idea's?
