I have just had to reload my PC with XP Pro for the first time since I brought it. Everything works okay, but in the Device Manager there is an exclamation mark beside the C-Media AC97 Audio (codec) driver. I can't find this on any of my CD's. It would appeat that I need this driver to make my speakers work.
I have tried trawling the net but all the sites that mention it don't appear to have the right files.
i think you should find out what is your mobo made and download the drivers from the manufacturer website. its the best way to get the right drivers. do you know your mobos made? you need to know exact model and tipe of the chipset.
use this program called Belarc to diagnoze your PC click here you will find out your mobos made and chipset very easy to use just download and execute the program give it try and let us now your mobo and chipset
I think what has happened is that you are looking for the realtek driver. However when you used windows update it has installed the C-Media driver onto your computer. This has overridden your Realtek driver. This has caused the sound to not work. The C-Media has a explination mark next to it because that driver is not working. Hope this helps.
