How to record audio file

Thanks a lot, but mine is still not working. This is what I did:
I use an RG to display list of all audios. Then on clicking on a cell, it takes you to another page. This page has Audio as type of content.

On page load, I upload the content to audiorecorder. Then there’s a workflow for play icon. When I click on the icon, nothing is being played.

What am I missing?
Please assist.

Thank you!
