This problem might have several causes. The first thing that you can do is to go to Start > Control Panel > Sound > under Recording and check if the volume for your microphone isn't turned off. This is the most common mistake encountered. If all seems fine, try to update your webcam driver. This is advised because the driver for the microphone is incorporated in this one. Also, a reinstall of Dell Webcam Central program might be a good idea. If none of this fixed the problem, take your PC to a service because the problem that you encounter could be caused by a hardware malfunction of the microphone.
