I use this to share a set of speakers between my work computer and my play computer. When both computers are on and have audio plugged in as sources there is noise in the speaker that disappears when the computer not in use is unplugged. It comes back if the second computers audio is plugged back in. It is still easier to manage plugging in and out of this unit instead of the docking station, but it is still not the perfect "push a button to switch audio sources" that I was hoping for.
