WHERE ARE THE FOOTSTEPS?! Chute sounds?! Zipline sounds?!

As someone who's played this game since launch four years ago and has suffered through countless audio bugs, this is decidedly the worst it's ever been. People sprinting behind me full speed, stomping up stairs, climbing ladders, zipping across or upwards, parachuting, bashing through doors, I can't hear ANYTHING. Anything at all!

I've tried all the mixes, I've turned 3D PS5 audio off.

I have a decent gaming headset and it's not that because my audio was just fine before this BO6 integration. Even the first couple of days of the integration was okay. The past week or so though, it's virtually nonexistent.

I'm not one of the haters of the integration, I promise you - I've actually somehow been enjoying all the changes (don't come for me please) but the audio is making it unplayable!

What's left to do? Pay £16 for the enhanced headphone mode?! It's bad enough I pay to see (specky four eyes and all) but now I gotta pay to HEAR? What the fuck is this bullshit?!

Am I going deaf at 29 or is it this game? Any help would be appreciated!
