Audio no longer plays at all

As of 12/12/2020, after an update on my Windows computer, my audio on FFXIV no longer plays. It is just FFXIV with this issue.

I am on PC and I have tried numerous ways to get the audio back, from:

-Changing my Borderless Windowed game to Windowed>Closing the game>Opening game>Going to Fullscreen mode
-Rolling back the Windows Update that happened on 12/12/2020 for my computer
-Updating the audio drivers
-Disabling and re-enabling my default output device within Windows Settings
-Quitting the game and re-logging
-Re-installing FFXIV
-Turning off and turning on Master Volume (In an act of desperation)

Editing to add, as of 12/15/2020, these methods did not work:
-Reinstalling Realtek HD Drivers
-Reinstalling my mother board's drivers
-Changing headphone jacks
-Using a different headset and earbuds

On both the Windows Audio Mixer and Advanced Sound Settings, FFXIV is set at 100 in volume and set to output on my default device, Realtek HD Audio but there is still no audio. I'm running out of things to try. All my audio drivers are up-to-date, and it's only FFXIV, no other games have no audio, so I'm wondering what happened and how to fix it. Please, send help.

Updating to add:
The Volume mixer shows that Final Fantasy XIV is playing audio. But there is no audio outputted to my headphones. Or on any headphones I tried.

Doe the error occur if headphones are plugged into the PC? Additionally wee any updates or changes made to the PC?

My headphones are connected to the audio jack in the back of my PC. There was only one Window 10 update that occurred right before the sound problems have occurred. No other changes were made.

I did roll back the Window 10 update but it did not help at all.

All playback devices are disabled except for my main one. In the audio mixer, the Final Fantasy XIV application shows sound playing on the device, but there isn't any sound when the game is open, even if I am tabbed into the game. All options for the sound are on within Final Fantasy XIV.

Does using a different pair of headphones resolve the issue? Is the issue only when using headphones or does this also occur when using the computer speakers? Is it possible to try a different audio jack?

I switched audio jacks and that did not work, and using a different pair of headphones does not work either.

Does the issue occur when using the computer speakers or only when using headphones?

I do not have speakers to test this issue on. This issue has only happened with all headphones I have tried to use.
