I have a z60t that I just installed vista on (not because i wanted to, it's just what I had avaliable). Everything else is working great, but I cannot get my speakers or headphone jack to work at all. Vista says that it has found "high definition audio device" and installed it, but says that the speakers are not installed. Under the "high definition audio device" it has two audio jacks, but does not recognize that I have integrated speakers. I have tried google, and nothing I have found works. Any suggestions?
