Powerpoint - related to audio?

I have made a powerpoint presentation for my dear. I added audio clips in it(wav format) as background music. But when i put the presentation in a cd and played it on another computer, it had no voice. I have checked all settings and without altering any settings, the same presentation plays background music on my pc but no where else. If i delete the source audio file from my computer then it is not even played in the presentation on my pc. So i think it is not audible on another computer because it has no audio files that i have used. So guys please suggest any way in which the audio will be audible when i gift it to my love through cd. Please suggest before 11th march, the file would be nothing without the background music
