With just having my X-T1 arrive yesterday and then going through the settings using advice from Setting Up The FujiFilm X-T1 I have yet to find a way to turn on the sound to allow the flash. I have double checked in the menu options etc, but the flash still fails to work as the LCD indicates that the sound is turned off.
Now I must say at first impressions using the FX 18-135mm f/3.5-5.6 lens I am very impressed with the sharpness and resolution of the images I shot last night, even though this was not the lens I was suppose to get when I ordered my X-T1, that is being handled and the FX 18-55mm f/2.8-4mm lens is being sent on it's way.
