The content here was a video that was uploaded to DTube. The video's audio was broken in the process. I will try uploading it again tomorrow.
To clarify, it seems that not all mp4 are created equal. An mp4 that seems to have audio and video attached, when uploaded do not always work as anticipated. The challenge here is to figure out what constitutes an mp4 that works.
I uploaded this, and for the life of me, I can't hear any of the audio. Can anyone else hear it?
Me neither
