Comment:

 @toddhalfpenny thanks for the report. Are you uploading the MP4 audio to
 the media library and then adding it from the media library as an
 attachment? Or are you adding it by URL?

 Unfortunately just adding the `mp4` extension to
 `wp_get_audio_extensions()` is not enough. Note that if you are in the
 post editor and you upload an MP4 audio file, and then try adding that
 media to a post it will incorrectly think that it is a video. The media
 logic I think is incorrectly only looking at the file extension to
 determine the media type.
