I am trying to install the audio driver on an HP Pavilion a820n and keep getting the error message "Can't find match Realtek HdAudio inf file". The file I downloaded is Realtek High Definition Audio Driver Update sp26552.exe from the hp website. I had problems with this computer before and followed the directions in a thread I started with a similar problem and you all helped me, but this time it's not working.
