How can I get my LCD television to play the sound for my computer?

I have a 15 inch LCD television hooked up to my computer.I can't get the sound to play when Im on my computer.I dont have any speakers hooked up to my computer because the LCD has speakers.I went to the volume controls and it still isnt doing no sound.What will I have to do to get sound to come out?

I'm sure that in the settings on the computer you can change where you want the sound to come from. Search around in the control panel or something. It's prbably set to external speakers at the moment and you'll have to change it to coming from the TV/monitor speakers.
