To check whether the speakers or audio cables are faulty, connect them to another computer or audio device, and test them.

Double-click on the Sound, Video and Game Controllers option, right-click on your sound card, and select Properties. Check the Device Status box to ascertain the problem, and select the Update Driver option in the Driver tab to fix a driver-related issue, or click on the Enable button to enable a disabled sound card.
