Powerpoint slideshow in Pocket pc

Haliza

How do view a powerpoint slideshow embedded / inserted with background voice
/ sound from mp3 / wav format in pocket pc?

I've tried several times, but it didn't seems to work. I've even tried
installing the Pocket slideshow, it allows to view & edit the slide and apply
the custom powerpoint animation effect, but it doesn't play the background
sound / voice inserted into the slide.

Solutions urgently required as we're in the midst of completing a project.

Thanks,
Haliza.
