Recently the sound on my Sony Vaio will play initially, but afterwards won't work. It doesn't say it's muted and the little green part that shows sound in the speaker area also doesn't appear when something is playing. I have tried to test the speakers to see if that plays sound but when I do it says that they are being used with another application and to close it before I try to test them, even when nothing else is open. If I restart it, the same thing will happen again. Why is this happening?
