Bug#587204: Impress Doesn't Play Audio in PPS/PPT Slides

Not what I see here. Every OOo version (also tried a bunch of
upstream ones) apparently fails to store the gallery sound in a ppt.
Loading a ppt originally generated from PowerPoint works though.
Please add more information on how exactly you created your
documents, or even better, make them available (especially the
1:3.2.0-9 - generated ppt you claim has the sound).
