The new gun sounds are amazing but the balancing is not there for other sound effects, foot steps, door openings, infected "screams" are all very quiet to the point where they are barely audible no matter what I adjust with the in game audio balances or on my PC side too. Infected sound like they are along way off in the distance when they are a few metres from me.
Similarly VOIP is too loud no matter what I adjust the VOIP volume too in game, the player I am talking to comes across very loud. The ambient sounds seem normal but the sound effects are too quiet, with VOIP too loud.
