I really hope this is fixed on release because this is a game breaker. Impossible to play when you start a mission with full audio and with each encounter it gets worse and worse to the point where there is nothing. It only happened to me on the private beta in the endgame mission but this time it is after any encounter with more than a couple of Npcs.
Such a shame because the rest of the beta is great.
It makes me wonder why they even released the beta at all with this issue.
My sound will cut in and out..or happen after the fact. While firing (any weapon) the sound will cut out and or occur on a sliding scale of quiet to "normal". Charging enemies either don't make sound until after they attack or..there is the constant charging scream with no enemies around at all. In one instance after a short confrontation all the fire arm sounds cut out..only to all play after I had left the area..and the deploy-able auto turret sound went off for about a minute straight..even though I had not deployed it.
Other than that some minor control glitches when interacting with crates that can be opened for resources (i.e. character locking up after opening the crate).
