Power Point sound integration issue

Hi Everyone,

I am having issues with Power Point. Tried to insert audio into my presantation. I inserted it successfully but as soon as I replace the sound file from its original place or delete it the audio dissappear from the presentation. I have tried with different audio format for example mp3 and wma. None of the are working. (the MP3's size is 10Mb and the presentation size is 15Mb)

How should I integrate the audio so it can be hearable on a different computer? (without the original audio file sitting next to the ".pptx")
