I'm not able to locate any documentation for which media types are supported. I have a new instance but trying to add *.mp3 or *.ogg files is not working. Is there a list of supported media types somewhere or does this need to be created?
Found this link to setup the audio plugin and pre-req, https://docs.mediagoblin.org/en/master/siteadmin/media-types.html, but it doesn't specify what is supported.
