Hi

Have you got the speakers muted by mistake

if you go to

start
control panel
sound/audio

and have a look in there to check if the settings have been disabled or not

this link will take you a site to get audio drivers http://www.realtek.com/downloads/ click on the one you would like then on the next page click accept and away you go


click save and save to your documents then click open or run


hopefully this will sort the problem out for you
please let us know if fixya fixed it for ya
