MP3s are not embedded into the presentation file, so when you send only the PPT
file you are sending it without sound. You'll need to send the MP3 file also.
I would recommend that you zip the two files together and send them with
instructions to unzip them to a folder on the user's hard drive and play the
presentation from there.
If you want them to be able to play directly from the email, you'll need to
embed the sound file. That means that you'll have to convert the MP3 to a WAV
file, since only WAV's can be embedded. Before doing this, be forewarned that
the WAV sound file will be about ten times larger than the MP3. You will also
have to do the conversion in some other software. You can do a google search
for "MP3 to WAV" to fine software capable of this, or you can purchase an add-in
for Windows Media Player 9. See
http://www.microsoft.com/windows/wi...tarted//Personalization/Plugins.asp#MP3Create.
Once you have converted the file you will need to move it to the same folder
where your presentation resides and then edit your presentation. Delete the
MP3, go to Tools > Options > General and change the "Link sounds with file size
greater than" to 50000 (which is 50 MB). Then insert the WAV file. Save the
presentation and check its size in Windows Explorer. The size should have
increased by the amount equal to the WAV file. Now you are ready to email it to
people.
