So yesterday I was switched my hd 7970 with 3 non crossfire 280x . After I was done i wanted to play a game so I launched the game and sound was not working. So i go in the control panel and there is only the sound card as playback device. So i go into realtek sound manger and if there is something plugged in the jack it normally goes brighter. Well as you can see in the pic it doesn't altough i tried 5 audio devices i tried to install a new audio driver. Nothing works i looked for fixes but everything that I tried failed.
