[QA] Audio files do not play

[jnweiger]

Tested with files_mediaviewer 1.0.4 in firefox and google chrome on Linux.

• No audio mime types are listed in https://github.com/owncloud/files_mediaviewer/blob/master/src/config.json
• After adding "audio/mp3", "audio/mpeg", "audio/x-wav", "audio/wav", "audio/ogg", "audio/oga", "audio/x-flac", "audio/flac"
  to both apps/files_mediaviewer/js/files_mediaviewer*.js files,
  • ogg and mp3 Audio files start the mediaplayer with an empty gray screen, but it does not play.
  • wav, flac, wma are still offered only for download with application/octet-stream mimetype.

The media viewer currently has a scope of displaying images and videos.

I would love to be able to play individual audio files without having to install the bulky music app
