Voice-Over completely broken

Hello,

When i started playing ARR there were voice over, but then it vanished, even if i rewatch the cutscene where i had VO, they're gone now. (for example opening sequence)

At first i thought that's normal, but while a cutscene i could hear voices in the background, as if they would be far away. (had to disable background music to hear it clearly)

Tried to reinstall FFXIV and update sound drivers, but that did nothing.

Is there a solution for this ?

PC:

Windows 7 Ultimate 64-bit
Asro Z68 EXTREME4 GEN3 Z68
i7-2600K CPU @ 3.40GHz (8 CPUs)
8GB RAM
AMD Radeon HD 7900 Series 3GB

P.S: Sorry for grammar mistakes.
