Hi, I guess I have the same issue. I also have a Dell Studio 1558 and the internal microphone (the one beside the camera) stopped working after I upgraded to Natty.
I never had problems with the internal microphone before on Maverick or previous versions. How to enable it through alsamixer? Let me know if there is anything I can do to help.
