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

When exactly did this start happening and do you recall anything changing on your PC that coincides with it?

Do you happen to have a dedicated sound card? Or is it integrated into the motherboard? What kind of speaker set up do you have?

Any additional information will be helpful in finding a solution.

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