First of all, i had to re-format my comp a few days ago. I put windows xp, used the motherboard cd to install drivers/hardware, and then installed updates. When i got done, my speakers dont work now. They are not individual speakers, they are built into the sides of the screen, but they still have plugs, one green, and one pink. So i tried to open volume control it says "there are no active mixer devices available". Then i tried to install the hardware (Audio Device On High Definition Audio Bus) and it said "the hardware could not install because i dont have the necessary software needed". So i went to Realtek.com and downloaded a driver (AC97), and the hardware still wont install! So what else do i need to do to get my audio working??? Please give me good advice, ive been working on this for 3 whole days now! Thanks for everyones help!
