laptop speakers not working vista

i downgraded from vista to XP on my laptop. now, the speakers are not working. will external speakers work?
i checked the compaq website. it says my speakers will not work.i dont mind. but will external speakers work?? all drivers are correctly installed.
no. the problem is with your sound card … right click on my computer click on properties then the hardware tab then device manager, in here you will see your soundcard specified with either a red x or a yellow “!” right click on it and install the drivers for it. (either from the CD that came with your computer or download them from the net.
