Flash Security Settings -- FLV audio files

 Maybe I'm just slow with this whole process or something? Sheeeesh! I cannot figure it out...I still can't hear the audio in my e-learning(s). I've checked the sound on the computer and everything is fine and sounds play on other/older e-learnings I've built, but not the new ones. Maybe I'm not changing the correct settings for the Flash Player??? I have no idea...
