I'm currently running Game of Thrones on Debian jessie with wine 1.7.38. The game works great so far, sound, gameplay and video sequences generally work. However I started episode 3 today and noticed that a fair amount of the voice sequences are missing. For example in the first part of the episode, I can hear Asher but the other two just move their mouths without anything being played.

I switched on subtitles so I at least understand what is being said but I would still be interested if this is a general bug in the game, a bug in the gog.com version or just a side effect of me running the game with wine instead of a native Windows OS. I already tried updating the game to the latest version available from gog, uninstalling the whole game, downloading the full installer again and installing the whole game again but it changed nothing.
