Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

When did this first start happening? Did anything change/update on your PC that coincides with this?

Do you notice any pattern to the crashes (only when teleporting, mostly in major cities, etc.)?

The "XAudio2" part of the error makes it look like an audio driver crash. Do you have dedicated sound card? What is your audio setup like?

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
