Alright heres the deal. I bought this macbook pro off of ebay, knowing that the sound didn't work, but I figured I could fix it. I guess not. One issue is that their is a piece of a headphone jack broken off inside of the hole for it. I figure that this might be disabling the speakers possibly. But the computer wont let me adjust the sound at all. I included the picture on what it does. and the settings panel. Why dont the internal speakers show up? I know they work because the laptop makes a sound when i start it up. It chimes.
