Here is the deal.
I have tried every possible so-called solution to fix this audio issue.
I have tried with all kinds of windows/game/headset sounds settings/combinations.
I have repaired the game countless times.
Re-Installed everything, including Origin thrice.
I've fiddled with sound quality on windows.
I've tried playing on speakers.
My third installation of the game was on a clean software/windows and drivers and only thing I have installed was Apex after the drivers.
Let me tell you one thing; It's not you. It's the game and the * servers mate. Don't change the settings which already are working as intended because people think that's fixed it for them.
It can't and it won't because the problem is on EA's/ Respawn's side. It might get fixed for a couple games just to be reproduced for no * reason. Even Dr. Disrespect ranted on this issue on live stream.
This probably will be my last entry because me and my friends are done with this game.
I hope you don't get cancer trying to play this game. It was fun but equally awful because of this particular and neglected issue.

Peace.
Edit: It happens on all platforms, not just Windows. So please, do yourself a favor and don't try anything suggested in regards to fixing the audio problem. Until it gets patched which I'm fairly sure will not because of months and thousands of complaints were there and they couldn't do jack sh.t and it's still there. Just because some people don't experience this issue doesn't mean it's working as intended. Apex took a giant hit in the ballz just because of these technical issues.
