As it stands I can't hear VOIP properly from other players except when there is nothing happening at all. VOIP is at 100%, but I have no control over ingame (gunshots, footsteps, explosions) sounds level. Master, Music, VOIP are the current sliders. Please add an ingame sound slider to the game.

Yea true its really soft most of the time i cant understand what they saying

I have noticed this, but I think the problem is user error and not the game's fault. You can boost the gain of your mic in windows which is what I have done.
