The only problem I've ever really had with that adapter is that on the some machines, you need to position it very correctly or else you are prone to ripping ports off of your board. I sometimes left the sound ports unplugged so as to reduce the stress on the cables and my 840av's board, although a solution today for me might involve a lot of duct tape, and simply affixing the audiovision adapter to the rear of my 840av. (that or getting an 8100)
