My microphone on my Hp Elitebook suddenly stopped working and I have tried different things to make it work but it has been to no avail. I have also called HP support for it and they have tried different things, but it is still not detecting sound. On the mic test, it detects the microphone well but I am still not getting any sound. I don't want to settle on the fact that it is a hardware issue because why will it just go bad like that externally.
