Fix the "loss of sound requires a game restart" problem

Just for a change of pace, here's a thread that isn't about the congestion and 5002 errors and queues... although it is related to them now.

Please, please, please fix it so that we don't have to restart the entire game to get our sound back if we happen to lose it (such as by dislodging a headset). I accidentally jostled my USB headset and glitched my sound, and of course unplugging and plugging it back in resulted in no sound at all from the game. Aaaand thanks to the monstrous congestion on my data center (Aether), I'm refusing to log out after spending almost an hour to get in. So now I have to play with no sound if I don't want to repeat that process, because for some reason FF14 doesn't work like any other game I've ever encountered, and doesn't automatically switch between headset and speakers.
