Version - Latest dev.
I found a very strange bug - the sound is greatly muted (almost impossible to hear it with other ambient sounds) when you turn your back on the sound source and look somewhere else. It does not matter if I am standing one meter away from tank or the NPC that speaks - engine, rotor, speech - the result is the same.
The effect is the same at command view.
This bug really affects overall gameplay.
I dont think it has something to do with my PC sound driver...
