So first - ALWAYS download the pdf section you are working on to your computer. Then open it up. Where you see a little speaker and a rectangle that reads "audio notes" you'll simply listen to the audio after clicking the speaker (little picture below this text). NOTE::: Often that embedded audio (in the pdf) will fail. It's not through my lack of trying. Apparently with the endless computer configurations it just isn't that reliable. SO -- I've a workaround :-) Just click the audio tracks that correspond to that particular section (further down this page. It's a simple listen and follow along.
