The volume level for the audio of CH321 John Calvin by M. Allen is so low I could not get the volume high enough to hear it in my car (when I usually play audio files for trips).
I am not sure if this can be fixed but its a pity I had to resort to the video on my home computer to listen to it.
I have not had a problem with the volume of any other M.ED audio levels I have.
It looks like we had the audio levels too low when we exported the videos for this course. We will fix this and get the videos updated. I apologize for the inconvenience.
