Identify your motherboard make and model. You can do this by 1. Look at your motherboard manual. OR 2. If you have a "brand" PC, check with the manufacturer OR 3. Look on the PCB, or actual board of the motherboard. Many manufacturers print their company name and/or model number on the motherboard, normally in the middle of the board or on a sticker on the northbridge chip. OR 4. Use the motherboard search list to help. OR 5. Run SiSoft Sandra then click on mainboard information icon and it will list the details.

Identify what sort of onboard sound you have by reading the product page for your motherboard or your motherboard manual. A VIA chipset based motherboard does not necessarily have VIA onboard sound. Links to VIA chipset based motherboard product pages can be found here.

VIA audio drivers should not be installed on those systems that utilize third-party audio cards. For third-party audio drivers support please contact your audio card supplier directly.

If you find that your motherboard does not have VIA onboard sound, note the name of the onboard sound you do have and follow the links to downloads or drivers on your motherboard manufacturer's web site to find the correct drivers and contact your motherboard manufacturer if you have any difficulties.

If you find that you do have VIA onboard sound install the drivers below, unless you have an Intel i81x/82x chipset (see note below).

VIA Six-TRAC Codec: Special Notes for VIA Six-TRAC Codec (VT1616) users

*Special note: VIA advises that where possible, users should install onboard sound drivers provided by their motherboard manufacturer in preference to the audio drivers above. This is because of the ID process in the Microsoft certification guidelines. Microsoft require a four part ID for PnP device drivers. If VIA have not received the appropriate ID from motherboard manufacturers, then the drivers below when installing on a system where the ID is not included in the driver package, will use the generic ID instead. In some instances, when this occurs, users may receive an error message or may even not be able to install the drivers. If this occurs, please contact your motherboard manufacturer for updated AC97 drivers.

Intel i81x/82x platforms only:
WMD and NT4.0 drivers for Intel i81x/82x chipsets can be downloaded from IC Ensemble's web site.
