After update 1.64 the voice of the player character, is too quiet! sometimes the first part of the sentence sounds quiet, but continued normally. Also the voices of the enemy infantry have distortion. It sounds creaked like an overloaded audio frequency.
I Changed my settings from 7.1 dynamic to stereo settings, like it became better a bit, but only for voice of player.
The voices of the enemies, sound sounds is still bad (distorted).
The voice of player still isn't good. When it the player's character to say, the first part of the proposal, which he says sounds a bit quieter and as if in the left headphone, and the second part of the sentence already sounds louder, but already in the right headphone. At the same time, the voices of the my subordinates, still have a somewhat larger volume, than the voice of the player.
