User uninstalled the drivers. Then downloaded Realtek HD audio and Waves MaxxAudio Pro directly from Dell site. Then installed them.
Two months ago the microphone was working well. But now it sounds like a very high and missing sound. And my sound does not appear at all. I don`t know if the problem is in my laptop or if it`s just a software problem.
