DOA

I now have Windows Server 2003 Enterprice edition installed and i now have a problem with my sound. When i play music or a game or whatever requires sound there comes a peep and it is really annoying, it peeps more if the computer works hard with something. I have tested with the LiveDrvUni-Pack but with that the sound doesnt work at all.. I didnt have this problem when i had Windows Server 2003 Standard edition.
