I have a problem on my audio

I have a labtop, and model of that is HP compaq nx6330.
I installed windows vista enterprise edition yesterday, but i cant hear any
sound.
Sound driver is installed, and if i plug earphone, i can hear sound.


How can i hear sound on only my labtop's internal speaker??

Make/Model of laptop?
