Laptop does not detect speakers

[soniclnd]

i have a dell laptop with windowsXP. about a month ago the speaker were working correctly but after some kid messed with the computer (maybe he deleted something)... now the speakers don't work.
when I go to control panel -> sound it says that there are no sound devices installed for sound playback... reading.... sound recording or anything when i go to hardware it shows this:
-LG DVD-ROM DRN8080B
-ESS Maestro 3 PCI Audio (WDM)
-Audio Codecs
-Legacy Audio Drives
-Media Control Devices
-Legacy Video Capture devices
-Video Codecs

can anybody help me?

Try upgrading your sound card drivers, some crucial files may have become corrupted, if there is not a newer version available, uninstall them completely and then reinstall them. If the problem remains, make sure that none of the volume control settings are muted.
BTW, this is assuming you checked to make sure all connections and cables were connected correctly and that your speaker system is receiving power. Hope this works for you, good luck :grinthumb
