Filled out what I could ISSUE: I've just recently installed Windows 7 Professional (retail, via the Engineering dept. of my University). Everything is peachy, except for the fact that my laptop speakers do not produce sound. When I plug in headphones via the headphone jack, I DO get sound (only through the headphones). I've searched all over many forums relating to sound problems and have downloaded several suggestions and have yet to work. --I have fully updated windows 7 via windows update. --I have all of my driver installation cds with me from the Dell manufacturer that came with the original computer (and I've tried a couple) --I've gone to Dell's Drivers & Installation section with my computer's serial # and attempted to reinstall the related audio driver with no luck. --My sound was perfect with the Vista Home Premium I was using earlier today. I'm just trying to get a driver that works. So far the links have been unsuccessful. If anyone could provide a driver that solved a sound problem that would be great (and I'd appreciate instructions). Thank you.
