Auto-mute in-game BGM while use PS4 USB Music Player

With the PS4 FW 2.0 updated yesterday, we can listening to MP3 via USB when playing FFXIV.

But when USB music is playing, it just plays over top of all the other sounds and music from the game. And it's based by game 'cuz some game (Such as Driveclub) can auto-mute in-game BGM while USB Music is playing.

It will be much bettter if FFXIV can auto-mute in-game BGM when we're listening music from USB. So that we don't have go system config and adjust BGM volume everytime we play or stop USB Music.

Hope that will be implemented soon. :)
