Problem in interactive pdf playing wrong sound file for all

Question

I have a created an interactive single page PDF with a video file and at least 4 mp3 files. I have added buttons to play one file and stop all others.
The buttons work perfectly BUT, the first click of any button actives a certain mp3 file. the same file each time. once i hit a button again that is told to stop the mp3 it stops and all works well.
How can i fix this issue of the one mp3 file playing one any media buttons first click?
thank you for any and all help

I've been working on displaying pdf from a servlet, and although I don't know exactly what your situation is, here is how I served up the pdf file from the servlet using the HttpServletResponse object.
            byte[] data = getFileBytes();// from somewhere
            response.setContentType("application/pdf");
            response.setContentLength(data.length);
            java.text.SimpleDateFormat dateFormat = new java.text.SimpleDateFormat("EEE, dd MMM yyyy - HH:mm:ss z");
            response.setHeader("Expires", dateFormat.format(new java.util.Date()));
            response.getOutputStream().write(data); //Write out the pdf report
            response.getOutputStream().flush(); //flush the buffer
