I am using a Dell XPS 17 L702X laptop. It is a new system that is purchased recently. It has as SSD in it. It is Intel 510. There are two hard drive slot in the same. I am having problem with the sound. I had copied a few video files. When I play them I am not able to get any sound. But I can hear in my headphone's. There is working fine. I want a bit help in making sound more proper.
