First of all let me say that I am an Tech idiot, so bear that in mind while trying to help.
I have a sony viao laptop. I have probably had it for a year and a half or so. Heres the problem....
The speakers only work part of the time. Seems like 75% of the time they do not work. On occasions they will start working out of nowhere, and then they quit the same way. But the most popular time that they decide to work is when the computer has just been turned on, or has sat idle long enough to go into "lock" mode and then unlocked.
Any suggestion????? I am sure that there are detials that are needed that I left out. So ask any questions you have, and I will try to answer them.
