conversation course problem

Hola, I see in the beginning of the conversation course pdf it says "Click on the Spanish phrase in the table to hear the correct pronunciation" this doesn't seem to work. I have never known a pdf to have audio embedded in it. Do you have to view it another way? Anyone know anything about this?

Yes, when this course came out a while ago, the document was in a different format. It had embedded links which when clicked on, the audio would be heard.
