The audio codec is the sound driver software for the motherboard.
Click on the link provided;
Scroll down to Sound: RealTek Codec Sound on board driver.
Create a folder on your desktop & name it RealTek. Download the file named: into the RealTek folder. When finished open the folder & uncompress the .zip file. You may need the program WinZip to uncompress the file. If you need WinZip you can download the trial version for free at this next link;

Uncompress the file into your RealTek folder. Open the folder & find the setup.exe file & run it.
If this fails to install double check your bios settings. Use the manual to help you. Make sure the bios setting for AC97 is set to [Enable] or to [Auto]. Failure to set this bios feature will cause windows to prompt you for the codec software.

You can post here if you still have problems.
Thank you for using Fixya
