Personally I've decided to stop paying my sub since the audio is ruining my game experience
It won't do much since im just a person but tbh it can't be my hardware fault, during the last update of SHB everything was fine and since 6.0 rolled in the audio got weird and its only on FFXIV.
If it was a hardware fault, why is it happening only and JUST only on FFXIV?

Seriously, audio is one of the highest points that makes a game good or bad... hope a fix will be there very shortly..
