I think I just figured it out.

For whatever reason when I record the voice it records it as a wam file. In order to have the sound as "contain in presentation" so once people donwloads the file can hear the voice it has to be a wav file. I'm not sure if this is the easiest solution, but was the only one I was able to come up with. Once the file is approved I'll be able to check if works.

(this rollyes is me looking at the sky praying that it works)
I still would like to know how people record their voices so it is a wav file. I had to convert each voice file and it was a pain....
