Recently, my motherboard (ASUS P4S533-X) was tampered with and we sent away for a new one with the warranty. I had a guy at my local computer shop install it. I brought it home and the sound isn't working. I have tried several sets of speakers/headsets to test sound and none work. The sound is on blast on both the speakers/headphones, and the Volume Control in the taskbar. I used the CD that came with the Motherboard to install the Audio drivers which normally works fine, but now it does not. I have checked and made sure that nothing was muted. The drivers that I installed via disk were AD1980 AC'97's. Installation went smoothly, but still no difference. Any suggestions?
