Did you switch audio devices?

This game doesn't support device switching well (or at all really). It sticks to whatever it launched in. The only thing it really "supports" is going from speakers to old-fashioned mm headset and back (assuming the same speaker devices are used)

For example, I have a headset that I can use in various modes (bluetooth 2-way, bluetooth 1-way, and as a regular headset).

If I start as bluetooth 2-way, and I change my device settings, I have to restart the game to get it to realize the change - even though almost every other application I use is able to do the change properly.
If I start as bluetooth 1-way, and I change, same thing...gotta restart the game
If I start as headset and switch to either bluetooth, same thing...gotta restart the game

The only way to get the sound back without restarting the game is to hook back up the original audio device it launched in.

And my absolute favorite:
If I start as either bluetooth setting (doesn't matter), and I disconnect my device entirely, it crashes the game Once again, no other application has this issue, just ff14.
