Hi guys, I use 2 HD 5770s in CFX and recently one of my AMD HDMI Audio devices stopped appearing in device manager. I literally cannot get my computer to discover it. I've tried switching the #1 and #2 cards and nothing is working. It seems like my 2nd card (newer one too) just doesn't have a HD Audio chip on it any longer. I'm wondering is this a common thing? The video card still works fine, it just is incapable of producing audio now.. Any help on the subject would be great!
