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

What audio devices are you using? Have you tried using different audio devices? If you have multiple audio devices plugged in, have you tried each one as the only audio device plugged in? We would also like to recommend performing a Clean Boot on the desktop to see if the crashing continues. This will prevent any programs from starting up when the starting when the computer first boots up. This can end up having adverse effects on the game when these programs are running in the background. To perform a clean boot for Windows 10: Open the task manager (CTRL+SHIFT+ESC) and select the 'Start up' Tab. Disable everything here and restart the PC.
