Hi dai.

The fix for not hearing the announcements and seatbelts and smoking signs etc., is to edite the FSX\Captain_Sim\767\sound.ini like this:

SoundOffWhenSimIsSlew=1              to            SoundOffWhenSimIsSlew=0      
SoundOffWhenSimIsPaused=1           to            SoundOffWhenSimIsPaused=0
SoundOffWhenSimDialogIsOpen=1      no changes
SoundOffWhenSimSoundIsOff=1         no changes

Those lines are right near the top so you shouldn't have any trouble finding them.

Hope his helps.

Mark
