The D-Link 2-port KVM Switch with Audio Support (KVM-222) allows a user to control two PCs from a single USB keyboard, USB mouse, and VGA monitor. Audio support allows the two connected PCs to share a set of speakers via a standard 3.5 mm stereo jack. This enables you to listen to music from one system while working on another. The KVM-222 is plug-n-play and requires no additional driver to run.
