Weird Sound Volume lose on Focus Loss

Hay,

i bought a new computer, installed Apex and encountered a weird sound problem.
When I dont directly look towards the sound source (like shooting enmies, footsteps,...) this specific sound gets so quiet that it feels like miles away.
This wasnt a thing on my last computer.
Just tried again in firing range. Termited right behind me. Sound was fine until i turned like 60° away from it. Then it droped to almost nothing on 180°. Allthough it was almost next to me.
Any ideas how to solve this?
Drivers are updated. This is the only FPS i have the issue with.

Thanks for help in advance
