I have done some detailed testing to do with the "depth under keel" and other officer shout outs not playing.
I can confirm that it most definatley has NOTHING to do with CaptHelms sound mod

. (Which is pretty obvious anyway as they are just sound files)
This issue occurs for me even without his mod installed. I have found a workaround for it however, just save and then reload, the sounds should now start playing. If the initial save and reload does not work try it once more. This works for me 100% of the time. This is more of a game bug than a MOD issue as far as I can tell from my testing, and looking for a workaround.
By the way CaptHelm, excellent job on this sound mod, cant bring myself to listen to the stock ones anymore.
Cheers
