I am trying to finish a Jeopardy PowerPoint for class, and have the 'Jeopardy Thinking' music to add to the Final Jeopardy slide. The music file is 175 kb, and is 31 seconds long. When I'm in editing mode, the entire file will play, but when I play the slideshow only 11 seconds will play. It even says the file is 11 seconds long, but still plays the full 31 seconds during editing mode! Any ideas?

Thanks!
