Where do I locate motherboard sound drivers?
Users who have motherboards with on-board audio (often with VIA, Realtek, or C-Media chipsets) may have issues with their audio or AC'97 errors in Device Manager. Often this is caused because the operating system has been reinstalled and the motherboard chipset drivers are not installed. To resolve this issue, try following the following steps.
Let Windows redetect drivers
If you have not recently reinstalled Microsoft Windows, it's possible that your audio drivers are corrupt. Open Device Manager and remove all devices under Sound, video and game controllers and any Other devices. Once removed reboot the computer and let Microsoft Windows re-detect the audio drivers.
Motherboard chipset drivers
Reinstalling the motherboard chipset drivers will resolve this issue. If your computer came with a motherboard CD, install the chipset drivers from the CD and the sound drivers if also available on the CD.
Sound card drivers
If after installing the motherboard chipset drivers, you continue to have issues install the sound drivers. We suggest you download the sound drivers from the computer manufacturer or motherboard manufacturer.
