Can anyone tell me what to do to get sound back on my computer? I have done it all . When I tried to extract the audio device it got to almost the end of the file & said error message 40 whatever that means. Every driver site I go to it says I have to pay & those I have downloaded do not work. When I tried to open them, or they just plain do not work. So I am at a loss as to what to do next. I just know I cannot not open the Analog Device 198 x intergrated audio on my cd. Thanks for any help. PS I even tried new speakers but it's not that.
