I recently updated my GATEWAY MT 6831 with Windows 7 and my speakers do not work. I have tried everything and cannot figure this out. There is a red x over the speaker icon but disappears when i plug in my headphones. I tried downloading the SigmaTel 9250 drivers but they are for VISTA only and will not install. And when i slowly pull my headphone jack out, the speakers will try to kick on. So i dont think its a driver issue. IDK but this has been beyond frustrating. Any ideas? Ive already done the obvious ones so please dont repeat control panel blah blah blah. I'm not a computer idiot (at least until now). Any help is great appreciated!
