Moin,

I've bought my game yesterday and wanted to have the original voice acting in the game,
because the German synchronization is not so nice,
game switched to English and you can hear almost nothing from what they say!
Why is that?

Dunno maybe the german dub was balanced too.. loud?

Go the menus and lower the sounds of everything but dialogue and then increase PC volume accordingly

The sound is everything on max up to the music

Polish dubbing is original voice acting :)

Try this:

Q.: The audio level is very low or missing when the game starts, during dialogs and cutscenes.
A.: The only solution up to date is to change your configuration to either Stereo (2.0) or Quadraphonic (4.0) until the game is fixed. (Cheers Red_Eagle_LXIX)

And if you really want to have the original voice acting in the game set the language to Polish like Extreme96PL said.

This issue has been around since release, and after 10 or more patches, it still not fixed, along with other main quest and side quest severe bugs, and other stuff I don't remember, what the hell is CD Projekt doing?

I know you probably have no clue, but will there ever be a fix for the english dub on the fmv's (all the scenes that are video) being too silent compared to the sounds of the english dub on the live rendered game?

I don't know. I'm just a normal GOG user.

yeah its just that Ive been searching around my self and cant seem to find any official responses about the bad audio balancing any more
