i have a fujitsu lifebook n series running off of vista. my speakers will work when i first turn the computer on, but once i am logged on to my name, the speakers won't produce sound. when there is supposed to be a sound, however (ex: i get a new message in my inbox), the speakers make a loud thud sound. when i ran speaker tests on my computer, nothing showed that anything was wrong.
k so you go to lonch.file and click on "speakers" then there will be some questions like "what site do your speakers not work on?" or "what program does it not work on?" this worked for me i kniw it will work for you 8)
