I want to create a flow that will play a random audio file from one of a bunch that are in a folder.
I'm assuming that the way to do that would have something to do with a send broadcast action, but I don't know how to fill in the information for the send broadcast action. Can anyone help me out?

You can use action Start Activity to open an audio file in one of the available sound players. The example 'Open mp3 file' available within the action should fill the required fields.
