No audio from XPS M1710 HELP

Hey everyone, for some reason my speakers stopped working. Headphones work just fine, but no audio coming from speakers. I checked to make sure nothing was muted, in the audio option in the controll panel. I even did a full reformat, with all the correct drivers, and still no audio. Has anyone had this problem? Is it possibel the speakers somehow got like disconnected from somthing inside the laptop? ANY help would be greatly appreciated! thanks!!!!

 

if headphones are working the i suspect some problem the with the speakers so I would suggest to Call DELL ( if under warranty )

or if you're bold enough to try to check it yourself then , check out this link
