This is for 4 machines but it would be what you're looking for. http://www.amazon.com/gp/aw/d/B001GQ9D2I?cache=ce7bc9f1a825bcd401a4caea294f193d&pi=SX200_QL40&qid=1407127290&sr=1-2#immersive-view_1407127309976
It had audio switching so whichever computer is active is the audio you will hear and supports dual monitor (DVI). Just hook up the dual DVI from the computer to the KVM for each computer and switch computers via the button on the switch.
