ALC660 sound


I started using windows 7 when the RC from was available. I installed it, and sound was bad. It was crackling. I downloaded "high definition" audio drivers for my ALC660 from and problem with my sound was fixed. Month ago, I sent my computer to warranty service(because of the monitor...), and today I installed Win7 again, but not from the RC ISO from Once again, I have a problem with my sound, but this time driver from doesn't fix that problem. Does anyone have any ideas?

Thank you
--------------- EDIT ---------------
The problem was successfuly solved. If someone has the same problem: I needed to download the realtek soundcard drivers from, run the setup as administrator and set the compatibility mode to windows vista.
