Re: Multimedia Audio Controller Missing...
I had this problem previously. Its simple.
Your new motherboard must habe onboard sound which Windows is seeing, but not seeing it as in use, because you already have a dedicated sound board.
What you need to do is enter the BIOS (DEL key on most PC's at bootup), and within one of the menu's, switch off the sound chip, by disabling it.
Since all BIOS's are different, I can't really comment where but you'll find it.
Then, just save and exit.
