I just received my dell vostro 3450 today, it's from refurbished so I just installed the win7 home premium came along. Yet after all drivers installed, discovered no sound coming out from speaker at all. So I tried to update the latest realtek HD audio driver from internet, result still the same. Try to plug in headphone and it works. Suspect to be the Failed Sense Pin issue, so go to dell diagnostic eSPA, yet no sound from speaker since the beginning of the test. And there is no such thing as Audio Controller among those devices... cannot locate "custom" option as well. Puzzle what happen to my laptop, it's more like the speaker never exist... the weird thing is, the external headphone jack did response plug in and remove notification in win7, it's not look like the failed sense pin issue to me... anyone have any idea?
