I have the Steam version of this game.

I played yesterday (for the first time) for about 8 hours. Today when I started the game all the voices are gone. I checked the audio settings and turned the sound of the voices all the way up and still no sound. I went back to a previous save and they are missing there too.

My PC is running Windows 7.

Quit your game then try reloading.

I did that. I even restarted the PC.

Still no voices.

OK, I just notice the cashe validation feature and now Fallout is fixed.

:biggrin:
