Hdmi no sound from pc to tv

Hi, my samsung tv was working just fine up until I installed a new graphics AMD driver (Catalyst version 15.7.1 and my hardware is a AMD Radeon HD 5670).
I don't know if I should just download an older driver or what.
The wierdest thing is that even if the hdmi is connected, I can still hear from other devices like my headphones, I tried in the control panel choosing which would be default but it remains in silence.
