how to embed a wav into pptx, not link

[coopci]

I have 51 wav files to embed into a pptx file. The largest one among the wav files is 961KB and 40 of them are smaller then 400KB, so I think it does not violet the limit described at http://office.microsoft.com/en-us/po...303071033.aspx .



Of course I changed the limit to 50,000 KB, and reinserted the wav files into the pptx. But they are still LINKED rather than EMBEDDED !!! I know this because:
1) the pptx remains small (smaller than 700 KB)

2) It shows an absolute path of the inserted sound in "sound option"

So my question is simple, how to embed wav files into a pptx?
