Question:
Where do I locate motherboard sound drivers?
Answer:
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 below steps.
Let Windows redetect drivers
If you have not recently reinstalled Microsoft Windows it's possible that your audio drivers are simply 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 usually 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.
If you do not have a motherboard CD, obtain the
motherboard chipset drivers from the
motherboard manufacturer.
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.
A listing of motherboard manufacturers and their drivers can be found on our
motherboard chipset drivers page.
