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

I'd like to get a but more information regarding your error:

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

When the game crashes, do you receive an error message or does the screen simply turn black? When this happens, do you have any control over the game or does it force close?

When using borderless windowed, you only get the audio issues, correct? You have no crashing or black screen issues? What kind of audio set up do you have?

Can you submit a Final Fantasy XIV system report? Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

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