OK we need to know your sound card to get you the right driver.

Is this a branded machine such as a compaq or hp or emachine? If so, please tell us the make and model number.

If you don't know or its not a branded machine, go to www.belarc.com and download the free personal audit, run the report and post the results here. It will also put up all your licence numbers, please remove those from the post.

When we have that information we can start on the serious help and get your sound sorted out.
