Sounds issues

[Steel]

Basically,
Im getting sound through my headphones but im not getting any out of my spearkers, its not a jack issue, because my speakers are intergrated (Laptop)
So any idea?
UPDATE: So i have system restored to an earlier date, did not effect anything, possibly hardware failure on the speakers?

Sorry To bump but I might be able to help if you haven't resolved the problem already.

I've got 2 Questions.

Is it in game or is it all the time?

And what type of headphones are you using.
