Like in title i don't have sound from built in speakers in macbook
headphones or external speaker working ok.
I have noticed that when nothing is connected to line out then there is red light from line out connector.
I know that built in speaker are ok because when i turn on my macbook there is sound but after system boot built in speaker don't work.

If its not the volume button thing, then it sounds like the same thing that happened to me, only I could hear out of head phones when they were plugged in. If its what I think it is then the micro switch in the line in, input that has gotten stuck. You could try a quick fix by CAREFULLY putting a cocktail stick in there and unjamming it. However its dodgy as doing that and its not guaranteed to fix the prob. So I would suggest taking it the Apple shop and they'll sort the problem out.
Hope this has helped!
