Audio Problem with Quicktime Player

When I am recording with Quicktime Player, I can't hear game sound or even general sound from the computer, but as I view the video, the sound has recorded. I downloaded Soundflower as people have suggested, and when I apply Soundflower (2ch) on my output and input in sound settings, (as that is what is obligated if you want to record the game sound) it records the game sound, but I can't hear anything form my headphones or built in speakers. Please help!
