Audio issues season 2

From the beginning i had issue with the audio(Massdrop HD6xx,HD650,Moondrop Lan+iFi Zen Dac v2)doesn't matter what i used or settings i used in game the audio is teribble.Can't hear any footsteps when enemy is aproaching just when he is at 1m from me and sadly this is too late,i'm dead,the same thing is with the tanks;if i go prone near a wall or just lying on the ground doesn't matter i can't hear that tank is close to me.In very rare cases i can hear some enemy footsteps but can't pinpoint,i don't know from wich direction is coming; up,down,left,right ... i hear footsteps everywhere and ofc i'm dead again.Believe or not this is a major issue on a triple A game,its annoying and force me to quiet the game almost every time i die because of the audio footsteps.Please don't tell me that you don't have the necessary resources to fix it.
