Default lost all sound

I played a video today and my laptop froze. I held the power button to hard restart it but when it came back sound was gone. Headphones and external speakers don't work. I tried removing from the device manager and the pc automatically reinstalled drivers, same thing. I did a system restore to when it was working, same problem. This is an onboard integrated soundcard. Its the Sigmatelaudio. I even downloaded the drivers from the Dell website. Is it possible that its burnt out?

when I click on sigmatelaudio in control panel it says driver is inaccessible please make sure it is installed and enabled. When I click on sound the speakers are not plugged in, that's what I normally use and refers to the onboard sound. Right now it has the digital output device (spdif)checked off and says working but nothing plays.
