How to make sound persist when Power Point file is used in different media [closed]

I'm using Ubuntu 20.04 LTS. I want to import audio from some location into a PowerPoint file (which I edit with LibreOffice 6.4.2) and then copy it to a CD and present the PowerPoint file.

However, when I copy the file to the CD and use it on a different Linux or Microsoft computer, it does not play the audio, as the audio link is not on these computers.

Is there a way of adding audio to a presentation and having it follow when the presentation is saved and burnt to a CD, i.e. making it a permanent part of the presentation no matter what computer one uses the file on?

Solution 1:

Libreoffice Impress uses relative location, so copy the audio files into the folder where Power Point file is located, import them from new location into Impress and then burn the folder contents into CD. Now the audio files will play.
