Sound Annotation

Question

Hi there.
I'm having trouble with the sound of my "Sound Annotation". I have read through the PDF Reference manual and believe that I have covered all the requirements to get this annotation to run smoothly.
It loads perfectly, displays the sound icon, but when I click on the annotation, the sound does not get played at all and no other window appears to prompt me to play the multimedia content.
Here's what I've done for my sound entries and actions...
[keep in mind that i am reading from a txt file to get the sound location path, this txt file is stored in a variable called "soundFileName"]
// CosObj Setup - Sound Annotation
// Create a Stream and and set its Key as "3DD" in the annot dictionary
CosObj stmSound = CosNewStream(cosDoc, true, fileStm, 0, false, CosNewNull(), CosNewNull(), -1);
CosDictPutKeyString(cosAnnot, "Sound", stmSound);
ASStmClose(fileStm);
// Set the stream's dictionary
CosObj attrObj = CosStreamDict(stmSound);
// Entries in a movie dictionary
// Key = subtype, value = Sound
CosDictPutKeyString(attrObj, "Subtype", CosNewName(cosDoc, false, ASAtomFromString("Sound")));
// key = R [samples/sec], value = 8000
//CosDictPutKeyString(attrObj, "R", CosNewInteger(cosDoc, false, 8000));
// Key = F [File Specification], Value = "/C/tmp/Sound/cat.wav"
CosDictPutKeyString(attrObj, "F", CosNewString(cosDoc, false, soundFileName, strlen(soundFileName) ));
// Sound Action
// Type of Action the sound dictionary describes
CosDictPutKeyString(attrObj, "S", CosNewName(cosDoc, false, ASAtomFromString("Sound")));
// Key = Sound, value = Stream
CosDictPutKeyString(attrObj, "Sound", stmSound); // I have tried passing many different values...i'm just not exactly sure what this stream value must be...first i tried passing the file specification path to the sound [which did not work].
Is there anyone that could help me solve this problem?
Thanks in advance,
Kristy

Hi,
I've been struggling with this Sound Annotation issue for 3 days now.
If anyone has previously implemented a sound annotation plug-in for Acrobat, please help me out.
The following function represents the way I've created the sound Annotation:
PDAnnot createSoundAnnotation (PDDoc pdDoc, PDPage pdPage)
PDAnnot newAnnot;
PDAnnot textAnnot;
char buffer[256];
char* description = "Sound Annotation";
DURING
// Rectangle Size for the Sound Annotation
ASFixedRect annotRect;
annotRect.left = ASInt32ToFixed(36);
annotRect.top = ASInt32ToFixed(792-36);
annotRect.right = ASInt32ToFixed(136);
annotRect.bottom = ASInt32ToFixed(792-136);
// Create an ASPage object
pdPage = PDDocAcquirePage(pdDoc, 0);
// Creates and adds Image Annotation to the page
newAnnot = PDPageAddNewAnnot ( pdPage, -2, ASAtomFromString("Sound") , &annotRect );
// Cast the PDAnnot object to a PDTextAnnot object
textAnnot = CastToPDTextAnnot(newAnnot);
// Open the annotation, set the text, and add it to a page
PDTextAnnotSetOpen (textAnnot, true);
// Add Contents to annotation
PDTextAnnotSetContents (textAnnot, description, strlen (description));
PDPageAddAnnot(pdPage, -2, textAnnot);
HANDLER
AVAlertNote(ASGetErrorString(ERRORCODE, buffer, 255));
END_HANDLER
return newAnnot;
The following are all the entries that I've used to to setup the sound annotation.
// CosObj Setup - Sound Annotation
// Create Dictionary and set its Key as "Sound" in the annot dictionary
CosObj dictSound = CosNewDict ( cosDoc, true, DICTIONARY_SIZE );
CosDictPutKeyString ( cosAnnot, "Sound", dictSound );
// Entries in a sound dictionary
// Key = subtype, value = Sound
CosDictPutKeyString(dictSound, "Subtype", CosNewName(cosDoc, false, ASAtomFromString("Sound")));
// Key = F [File Specification], Value = "/C/tmp/Sound/cat.wav"
CosDictPutKeyString(dictSound, "F", CosNewString(cosDoc, false, soundFileName, strlen(soundFileName) ));
// Sound Action
// Type of Action the sound dictionary describes
CosDictPutKeyString(dictSound, "S", CosNewName(cosDoc, false, ASAtomFromString("Sound")));
Once again, the issue solely lies on sound. The annotation loads perfectly, just does not play any sound. ... the sound is read from a file and loads the location path of the sound.
Please, I am desperate and determined to resolve this issue.
Thanks,
Kristy
