Trying to fix my su27/33 RWR sound.

I have a weird issue with my su-27/33 where instead of my beloved missile launch warning beeping, I hear "missile, missile!" like in a f-15c. Everything else works fine though, I get normal scan sound, normal continuous lock sound, but not the missile launch, and it drives me nuts that I can't fix that. Did anyone have this kind of an issue, if so, how to fix it?
