Hi all

I'm creating a book in epub format and I need to link to **external audio files**.
Using local files is not an option, because I want to keep the epub small and easy to share.

After a few tests I see that the external link is correct when using the HTML output.
When I use epub, however, the terminal output says that it could not find media and skipped it. I extracted the XHTML file in the epub and it contains a not existent file path:

<audio controls>
<source type="audio/mpeg" src="media/file0.mp3">
</audio>

Please note that the file I'm testing is on Dropbox and doesn't have a "regular" URL. As explained in the Dropbox help pages¹, you must add ?dl=0 to cause the browser to donwload the file instead of viewing the Dropbox web page. As I said, this link works fine in HTML but it doesn't in the EPUB format.

I could find only this previous discussion² and it doesn't help.

Thanks in advance
Federico
