I had my phone hooked up to my computer to take videos of my kids off. To be honest, I'm not really sure what I did, but I have a feeling I accidentally deleted something important, because now, when I take videos from my phone and put them on the computer, there is no sound. They still have sound if I watch them on the phone, the sound is fine. Does anyone know what I might have done and how to fix it? Any help would be GREATLY appreciated!!
