Also been getting this issue since Endwalker dropped. I was gritting and bearing it before now, but this patch somehow made it EVEN WORSE. I went from sort-of-stuttery audio in the Endwalker MSQ fights, to the fourth fight in Pandaemonium being so completely ruined that I had to mute the audio entirely. I have tried all of the fixes, including the ones suggested by SE themselves. I have reinstalled every single driver I can think of, including audio drivers. I had ZERO ISSUES BEFORE ENDWALKER EARLY ACCESS. Audio team, you screwed something up royally implementing that stupid spatial audio, and now the entire playerbase is having to pay for it. This should've been a priority fix week one, not something that's still an issue nearly 20 days later.

Completely ruining the experience. Soken would be sad.
