I recently had to wipe my hard drive and reinstall Windows XP on my Emachines W4685 which I had rebuilt, and had a new ASRock P4vm800 motherboard put in. Everything was going well when I noticed that there was no sound. I went to the Emachines website and downloaded the recommended driver by the company Realtek AC'97 Audio Driver, but there is still no sound..........does anyone know how to remedy this problem?
