First you download the audio driver and extract it into a directory(for instance, C:\audio driver) in your harddisk. Then you go to "Dervice Manager" and "Sound, Video, Game Controllers" If you can see any audio driver, click once on the wrong driver, then use the right mouse button to click once on the wrong driver, then use "update driver" to update the audio driver with the new sudio driver you have extracted.
