Created attachment 38858 [details] Patch
Does this need to be on XSLFPictureShape? Aren't sound and pictures different things?
According to http://officeopenxml.com/prSlide-multiMedia.php: "Multimedia such as a video or audio clip is added to a presentation as a property of a picture or shape". And PowerPoint does create a <p:pic> element with the structure described in the linked article when adding an audio: <p:pic> <p:nvPicPr> ... <p:nvPr> <a:audioFile r:link="rId2"/> ... </p:nvPr> </p:nvPicPr> ... </p:pic> Please see the test file from the patch as an example.
