Steps:
1. severe audio stuttering of music, sound effects and system effects, combined with a slight lag of these sounds, occurs in combat, when other players are in combat, when crafting, when gathering, when idling in main areas, in private housing, or in instanced areas, when underwater, in loading screens, during cutscenes; none of this occurred before the release of Endwalker early access; certain duties, such as Smileton, consistently have much worse stuttering than others, such as Stigma Dreamscape, which works nearly perfectly
2. Turning the camera to face my character stops the stuttering, even when there are still many characters on screen with many combat skills going off
3. Set listening position to 100
4. Set equalizer to standard
5. Set all sounds to 100
6. Muted ambient sounds
7. Unmuted ambient sounds
8. Reduced all graphics settings
9. Limited FPS to 60
10. Restarted game
11. Set priority of game to 'High' in task manager
12. Disabled USB selective suspend setting
13. Confirmed computer was on 'High Performance' power setting
14. Switched processor scheduling to 'Background Services'
15. Exited all other programs
16. Set sound settings to 16 bit, 44100 Hz
17. Confirmed sound drivers were up to date
18. Switched to DX9
19. Confirmed no gamepads were connected to computer
20. Disabled unused audio output devices

The only one of these steps that had any effect at all was setting listening position to 100. With this setting, turning the camera to face my character stops the stuttering. When this setting is at anything other than 100 or close to 100, turning the camera to face my character does not stop the stuttering. Again, turning the camera to face my character stops the stuttering even when there are dozens of players and npc mobs on screen with combat skills going off. When the stuttering happens, I monitor FPS, which does not dip even a single frame.
