Hi I have a sony vaio S 580. It is just 6 to 7 months old. It has been working good and all of a sudden the laptop speakers dont go off. Even when i connect the headphones, the laptop speakers are on. my headphone works good. I checked with different headphones. There is something wrong with the laptop. When i called sony guys, they made me reinstall my sound driver. But it didnt work. Now they want me to send my laptop to them for service which is really impossible for me as they take atleast 10 days. 10 days without a computer, is going to be a huge loss for me. Please help me out.
