The sound card driver is working properlyCheck to see if the driver is working. Click the start menu, right click on the computer icon, and select properties. On the left hand side under task select device manager and select sound, video and games controller. Double click on your sound device to bring up the properties page. From here it will tell you if your sound card is working properly or not. If it isn't try reinstalling the sound card driver. If the sound card is not showing up at all, then it might be defective.
