sound during preview no sound on playback


I have followed every tutorial i can find and have everything in order and ready to sync. In the sound editor the audio plays fine along with the sample mouth positions and when i play back in camera view my custom mouth positions are all lined up accordingly with the audio and are moving as if to the words. the only problem is i can’t hear anything. The “turn on sound playback” is in the on position. Knowing the software has acknowledged the audio and has mapped out the mouth positions, what might be the problem? Why might I be able to hear sound during editing and audio by itself, but not during playback?

Thanks, Matt
