Thank you for the reply Devirius.

The game will utilize the default audio device for it's sound. It looks like the crash you are getting is related to the audio. Unfortunately, the error doesn't tell us exactly which audio device is the issue though. In order to rule out potential variables, disconnect any additional audio devices that are plugged into your PC (speakers, other headphones, etc). Some controllers (like the PS4 controller) can be read as a speaker because they have a headphone jack. Unplug these as well.

Update any audio drivers you may have. You may want to update your graphics drivers as well. Nvidia has it's own audio drivers that may not have been updated if you don't intend to use them, so double-check those as well.

Perform a clean boot as well. Simply open the task manager and select the 'Start up' tab. Disable everything here and restart the PC. This will make sure that no background processes are interfering with the game.

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