Overview
There are two ways to fix the sound cutting and none of them take too much time.The first one (it won’t work forever)Save the game, after you can’t hear anything, and then, load that save. Everything works perfectly fine, now.It won’t work forever, because the savegames are limited, depending on the difficulty chosen by yourself.The second one (it works as much as you need)Pause the game, go to options, then to the sound section, and modify the value of all those categories. Just move those points around and change the volume. Now, when you’ll resume the game, the sound will be back.
