I have a sony vaio laptop,
It was working just fine yesturday but when I turn on the computer again it was already on mute.
so I tried to unmute it and it didnt unmute
and when I turn the volume up it only went up one and wouldn't go up farther, and when it went up one the little icon and it still stayed mute
so I went on sound mixer and it said "no audio device is installed"
i dont know what to do
can you guys help me ???
(oh if I spelled anything wrong sorry im a bad speller)
