I have C2D E4500 mounted on Abit IP35-E. Yesterday I installed Windows 7 Ultimate 64 bit. Working smoothly so far except sound. It automatically loads some drivers for it, but sound is not working with them. I downloaded drivers for Windows 7 64 bit from Realtek site (R230), but they're also not working properly. Anybody facing same problem?? Whatz the solution for this??
