Got a bit worse for me after the update.

Problems I'm having are pretty similar to others; Crackling/Stuttering sound during combat but spinning the camera a bit makes it go away for a second. It's starting to happen to me while gathering too. Loading screens crackle, Old Sharlayan crackles in areas like the Studium though not in the Aetheryte Plaza so it might not be a player model density issue. All I know for sure is that this new sound engine has ruined the playability of the game for a lot of people. I can still play for the most part, but I have to mute the sound for some instances because it just gets way too irritating. Hopefully they keep looking into this.
