My computer had a virus and we got it rebooted and after getting it rebooted there is no sound but when I go on device manager and check it says the sound is fine and games that require sound are playing I think it has something to do with the settings. I went and checked almost all of them and there seems to be no problem last time there was a similar problem and someone sorted it out they sound sound was going in as an input and not coming out as an out put if this is the problem does someone know how I can adjust and if this is not the problem what is the problem. I have windows 7 unlock iphone 3g
