I have the same audio issue. I am using a Bose headset. Whenever I turn it on, my game would crash with a Direct X error (ffxiv_dx11.exe+XXXXXX). I can always use my PC speakers for the time being but then I won't be able to use my mic for discord. This only happens ever since EW comes out. Is there a way to fix this from my side or will it be a SE issue to fix?
