I can plug in headphones and I get sound, but otherwise, nothing. This happens regardless of whether I start the game up with headphones in, or not, and even if I plug headphones in and then unplug them while playing. I've tried restarting the game and my computer multiple times. I've also checked FFXIV-specific sound settings in Windows 10 - they look fine.

I'm on Windows 10 Pro 1903. My last updates were these:

Happy to provide any additional information that's needed.
