I think I deleted multimedia audio controller from my computer, how do I get it back, there is no sound coming from my computer.

If you are using windows Xp, first of all make sure that the drivers you are using are meant for Xp.If correct sound driver is not with you ,right driver can be downloaded from DriverGuide.com (printer drivers, cdrom drivers, modem drivers, sound drivers, mouse drivers, monitor drivers, etc.) - DriverGuide.com .If you need more help,please give all details ,including fault symptoms, of the sound problem(s) you observed .
