So I did a clean reinstall the other day but unable to get sound on my dell dimension E512 desktop computer. I have installed drivers until I am blue in the face. Basically when I go to into Device Manager and there are exclamation points over Sigmatel High Definition AudioCodec and Multi Audio Controller. I have reinstalled drivers, restarted the computer, down all that I can do. HELP!!! I am about to go all office space on this computer. :(
