btw, mind you i did not read all 26 pages, a solution i recently found for audio issues that started with the release of endwalker was to unplug the ps5 controller i had plugged in for ps5 remote play. it seems that even though everything to do with it was disabled, the game was still trying to use the controller for everything i had disabled. not had any audio issues at all since i unplugged the controller. so if you have a controller like that in use, try to disconnect it, not a good solution but at least worth trying.
