It's an HP laptop. I get no sound. There is a button you press to turn sound on and off. It's orange when off, and blue when on. It won't turn blue when I touch it.
I had a problem with my sound once on my PC and had to reload the sound drivers using the cd provided upon purchase. I'm not sure if this is the same with laptops.
I got it to work that way, but the button ( mute button ?) that you used to be able to just touch no longer turns from orange to blue. It must be a bad contact.
