Adding an mp3 (attaching it to something with the Interaction... > Play

also tried moving it around and the link keeps working.

What I know is that having sound or video in MS PP has always been hell,
and when needed I always keep an external player opened.

Although it's impossible to convert everything. LibreOffice basically
uses XML, if Powerpoint uses some windows-specific trickery, say using
media player or similar, to play the files it's impossible to 'convert'
that in the format...

True. In fact I see a more general point in having the possibility to
export presentations in more portable formats taking advantage of HTML5,
SVG and the new browser technologies.
If you could save your presentation in a format which run in any modern
browser that would probably solve your portability problem.
