card driver is installed. To do so, use the following steps:

1. Click Start, point to Settings, and then click Control Panel.

2. Double-click System.

3. On the Device Manager tab, double-click Sound, Video And Game Controllers.

If a sound card driver is listed, you need to determine if the driver is
configured correctly. Contact the manufacturer of the sound card for further
assistance.

If a sound card driver is not listed, use the Add New Hardware tool in Control
Panel to install the sound card driver.

For more information about how to use the Add New Hardware tool, please see your
Windows printed documentation or online Help.
