No Nuke Explosion Sound?

[JRMedved]

OK, so I have no idea what or why this has happened, but I can play the game no problem, but I've noted that I do not have a sound when a nuke detonates. I also noted that I do not have a depth charge sound, and I think that crying woman sound is missing also. Everything else seems to be working fine. Dug around a little bit but I cannot figure out what the problem(s) may be.

Not sure why this has happened or where to look to resolve this. Hoping someone(s) can point me in the right direction.
