Hello, since I started playing Portal 2, I come on this forum for a small problem. So here, for the solo, there is no problem, makes the sound good, no break in the dialogues etc. It was at the co-op that it gets stuck. First, the ambient sounds are much too strong. When the robot moves, we swear an evil giant march 2 cm from my ears. In short the sound was good early on but now within two days I was unable to figure out what really happened here and why I am unable to get the perfect sou8nd on the game.
