Hi 
Hmm, if you make a copy of a DocX (and Odt) then you can rename the
file-ending from .docx to .zip. Then a double click opens the file as
though it's a normal zip-file. The audio part is probably saved in a
folder inside there.
However i get the feeling that the audio component IS already in the Odt
but just not playing correctly and i don't know why.

Here, Tom,
is what I did - while, like you, convinced that the audio file is already
contained in the pps (after all, it works find with MS Powerpoint), I
decided to use VidtoMP3.com's service to extract it from
4peonies.com/VanGogh.pps and then, after checking that I could play the
resulting .mp3 file in VLC, attempted to insert it into a .ppt version of
the original presentation file. After doing so, I renamed that file back to
.pps and tried to play it on Impress. To my surprise, I now got the music,
but the images did not automatically presented in succession, as expected
and as they had previously. When I pressed the space bar to initiate the
image presentation, they were presented in succession, but the sound
disappeared !...
My Impression (pardon the pun !) is that Impress is one of the weaker
elements in the LO package, as compared, e g, with Writer and Calc. I'd
very much like to see some comment on this matter - and hopefully
suggestions for remedying the problem - from one of the LO developers who
is working with Impress....
