Just recently, I noticed that sound through my speakers and headset was a little ‘buzzy’. I don’t remember doing anything to make it so, no updates or anything like that but, suddenly listening to music was not a pleasureable experience.  So I set off in search of drivers.

The RealTek website is presently sporting version 6243_Vista_APO which, if downloaded and run, should clear up your ‘buzzy’ sound just as it did mine.
