So in your case I can assume it is the Arctis Pro Headphones.

Search in windows for sound settings > sound control panel, and disable all audio devices other then 1 of the headphones. You could see if disabling only 1(the chat earphones one) would be enough.
This usually works because the user has a blank entry for FFXIV in the windows mixer settings, if the entry is not blank all devices can stay enabled without concern, minus a few cases where the system is experiencing USB controller hub resets (a problem common to Ryzen 3000 and 5000 cpus)
