When asking these questions including the model can sometimes be useful as some have interesting quirks that the reader may know about. One example related to this is the Dell 3380. The correct sound driver is Realtek and it will download that driver but If it is on the older BIOS then it needed the Microsoft High Definition Audio driver for sound to work. Once we installed that driver or updated the BIOS then it would work. How is this related? Because sometimes it broke the camera as well.
