HI,

 

I use a MacBook Pro and until today the sound worked fine. All of a suden the sound doesn't work, having checked the sound settings there is no option to select internal speakers the only available option is 'Optical digital out port'.

 

Any sugestions?

 

Thanks

MacBook Pro, Mac OS X (10.7.3)
