Need help finding a driver for the stated sound card. The codec given to me is CS4281.WDM, and there is a number shown under driver and that is 5.12535.0, asking for what that number is really for.

Some places you may not have tried.

You will need the numbers off your sound card chip, or the top 1 inch of your sound card, or the paper label on the back.

Thanks much. Found the driver.
