Some wav files in main sfx file dont play
 

Using DWEdit I can see various sound files are associated with launchers, but they do not play. For example, when surfaced in a sub, next to an Hermes CV firing cannon, you dont hear the "Fx_ciws_fire.wav" file play, even though the entry in the DW database seems to indicate it should, as it is the sound for the cannons on that ship according to the DW database. Basically i dont get any launching sounds from any ships weapons, just the ambient inflight sound. There seems to be many sounds (checked out in SCSoundEdit) in the main sfx audio file that are not playing. I have checked on another system and its the same thing. Can anyone shed any light on this.
