Hi, i have just reformatted my comp and did a windows 7 clean installation. However, after installing all the drivers, i could not get the sound to work. I am using asus P5K SE motherboard. In device manager under Sound, video and game controllers, there is "Realtek High Definition Audio" that is working and updated. Under Control Panel -> Sound -> Playback, there are Realtek High definition audio and it is working. Any help would be appreciated!
