You are going to have trouble as long is the sound is large because you
are going to have to email the sound embedded in the presentation or
separately from the presentation, but either way you are going to have to
email the sound. You might try converting the sound to another format
that is smaller than WAV. Alternatively, you could delete your sound, go
to Tools > Options and click on the General Tab. Set the "Link sounds
with file size greater than" to something small (it defaults to 100KB),
and that might be a good size for you. Then, reinsert your sound. It
will now be linked instead of embedded in the presentation. Be sure you
look at the information at "Sounds/Movies don't play, images disappear or
links break when I move or email a presentation" from the PPT FAQ:
