The amd high definition device is only required audio when using an hdmi connection to an external display, so it's not the cause of your current audio problem. open windows control panel, open device manager and open up sound, video and game controllers - post back with the full names of each device listed here..

Intel display audio is the hdmi audio sub-section of the graphics driver and is under sound video & game controllers. when intel came out with the "i" cpu's, they integrated the graphics into the cpu like amd had been doing for years..
