Same issue as everyone else. Never had a single audio problem in the year of playing FFXIV before Endwalker's + Spatial Audio's release, 100% smooth sailing! But now I can't avoid it. I've tried literally everything imaginable to no avail. It specifically happens for me if I move my camera an inch, and then it persists forever, unless I completely stop moving for a full minute. It causes headaches, I can't play with audio anymore, which is one of my favorite aspects of the game. It also happens in the Char Creation menu, when I get to the part where I'm either choosing a god or a server.
Woke up today excited; two weeks of waiting for a fix and all that. Nothing of the sort released today! Myself and many others have held off on playing Endwalker, the most anticipated expansion thus far, so that we could fully enjoy the lovely work the team put into the music & voices! And.. we still can't after a supposed promised fix that seems like it didn't actually come. Extremely cool. It's frustrating.. you clearly broke it, so you need to fix it. This is non-negotiable.
