We have a sound card in your computer, but Windows does not recognize.
For Windows to recognize your sound card, you must find and install a compatible driver for your sound card. Most sound cards require driver software to work properly. Make sure you installed any software discs that came with your device. If you have a disc or software disk does not solve the problem, follow these steps:
1. Check if a driver is available for your sound card from Windows Update. For more information, see Install Windows updates.
