I have a Vostro 1510. I somehow removed my audio output device and no longer have sound. I tried going to the drivers and downloads page to see if I could download a new device and attempted to download the Realtek that was provided, but when I tried to install it, it stated I did not have a driver installed. I also already have the realtek on my computer, and when I click on that it won't work because it says no audio devices are installed. What do I need to do to get sound back?

Thank you
