Did you by any change reduce the master sound, in-game at any point? Replays use a separate preference file, and therefore have that set to 100. When you join a game, the 'real' preference file is used and the master sound volume may be different there.
Sound too low, but ONLY in a game
@popsniper Jip means the in game sound settings, but I was also curious about the windows settings so it’s good you checked that. In game settings might be messed up in the audio tab.
I checked the in-game settings also, and all settings are set to max volume. I even checked the Windows mixer and all are set to max volume. Finally, I tried to play one of the multiplayer campaign scenarios and very low sound there also...couldn't even hear the cut scene sound.
@popsniper said in Sound too low, but ONLY in a game:
I reset the headsets to surround sound
Have you examined the log file yet ?
