Hi,
I also have the Dell E5520 and had the same problem, please also check that your webcam is working. The microphone is located next to the webcam and both devices were not working on my laptop. To fix it I have to remove the plastic surround to the screen and unplug the connector next to the webcam, and then plug it back it. Windows then recognizes the webcam and the microphone. I have to do this 3 or 4 times a week.
Sometimes just removing the surround does the job, it's clearly a problem with wiring/connector that is causing the problem.
