I have a problem on my dell laptop (XPS). Last night, the speakers (the one that is in the computer) was working but I don't know if my brother used/did anything. Whenever I play a song (from a CD) of windows media player, i dont hear anything. I make sure its not on mute and also that wmp is not on mute. I tested it again of another site that plays songs and i got the same results. Can some1 help me out?
