Greetings fellow Eorzean,

I'm sorry to hear that you've been experiencing audio issues. Have you tried updating your PC's audio drivers by any chance? If you have, it might also help to uninstall and reinstall any sound drivers you have. Also, please be sure to set the desired audio device to 'Default' in your devices sound settings. I would also suggest trying to perform a clean boot on the PC to see if any other programs might be interfering with the game's sound. To do this, start by opening up your Task Manager, and navigating to the 'Start Up' tab. Once there, disable all applications listed, and restart the PC.

I hope this helps! Thank you for posting in the FINAL FANTASY XIV Technical Support Forums!
