I just purchased an Asus G51VX gaming laptop and my headphone jacks aren't working! I reformatted the computer with Windows 7 Enterprise too and now it still doesn't work. The sound plays through my laptop speakers but when I plug anything into the headphone jack, it still plays through the laptop speakers. I have already run Windows Update (no more updates found), I have updated my Drivers via the Asus website, even reinstalled everything that came on their driver-utility disk so now it has a bunch of crap ware. I have tried plugging in different speakers and headsets and still no cigar. The Realtek sound manager also doesn't show that it's detecting any of the jacks when I plug stuff in... could it be the headphone jacks are busted? Please say no guys!
