[Solved] Stupid audio not work. Audio Player doesn't appear!
It doesn't replace URLs. You should put Audio content provider URLs not Audio file URL. For example SoundCloud URL. This is an embedding addon, it does embeds of content providers.
If you ant to upload an Audi file and display it with player, you should buy Advanced Attachment Addon. But please note, this addon uses browser HTML5 player and this player support limited file extensions.
