Review on StarTech.com 4-in-1 Dual Link DVI and USB Cable with Audio & Microphone - 6ft (2m) (DVID4N1USB6) - Black by Ryan Olsen

Good cable, built-in speaker, microphone, USB and DVI. But the audio cables are short. When connected directly to a KVM with all connectors aligned, the thick DVI cable can pull out the audio cables. Please note that this is a very rigid cable. Also, it's a DVI-I cable. This means it has 4 small pins around the paddle for the analog signal as well as pins for the digital signal. Not only does this connect to a digital jack blocking holes for 4 analog pins. I also tried prying out the 4 analog pins with pliers only to find that the digital jack uses a narrower spade so it still doesn't make a connection. So this won't work for you if you need to connect to a digital adapter via Displayport.
