I hate to say it but my issue just... stopped? After reinstalling drivers and the entire game did nothing I took a break for a couple days. Figured I'd play some duels where the audio bug isn't that much of a hassle and.... it was gone like it had never happened.

Yes identical to what you have linked. I haven't played any other fps games recently, I'll test it out.

I have the exact same issue starting after the recent hotfix: https://mordhau.com/forum/topic/19858/positional-audio-bug-cant-hear-behind-me-after-rec/#c3

Reinstallation of the game didn't fix the problem for me either. I haven't tested any other fps games to see if they also have the issue.

At least one person in a duel server yesterday they had the exact same issue. They didn't seem as bothered by it as me, the game is unplayable in team game modes, I feel like I start to get dizzy as the sound comes in and out. Duels are more bearable as usually nothing is going on behind me

Positional audio is broken for me since Patch #11 hotfix

Positional audio broken for me after 9/11 hotfix patch, working last on 9/10. I've also posted this to reddit (https://www.reddit.com/r/Mordhau/comments/d2z9wq/positional_audio_bug_cant_hear_behind_me/)

Audio working correctly last night, before the hotfix. Starting today I can't hear shit behind me. Noticed it immediately joining Invasion and confirmed in local match, if I run directly away from the ai I literally can't hear them swinging at me. Left, right, and forward are all good.

So far what I've tried:
Uninstall and reinstall audio drivers (requires PC restart)
Verify integrity of game files in steam
Update graphics drivers
Uninstall & reinstall Mordhau

no improvement so far, even after reinstalling the entire game I still can't hear anything behind me
