What is with the four \ for each command? I've never seen that.

Subject: [MiKTeX] MikTeX 2.9 beamer sound

Hi,

I'am new to beamer. I would like to create a pdf-file including sound in a wave file. Here is my Latex code : 

\\\\documentclass[11pt]{beamer}
\\\\usepackage{amssymb}
\\\\usepackage{amsmath}
\\\\usepackage[frenchb]{babel}
\\\\usepackage[T1]{fontenc}
\\\\usepackage{eurosym}
\\\\usepackage{multimedia}
\\\\usepackage{beamerthemeWarsaw} %Oui
\\\\usecolortheme{default}
\\\\usefonttheme{default}
\\\\useinnertheme{default}
\\\\useoutertheme{default}
\\\\title[Algorithmique]{Initiation à l'algorithmique} \\\\author[J-F Challe.]{Jean-François Challe} \\\\date{Le $1^{\\\\textup{er}}$ décembre 2012} \\\\logo{\\\\includegraphics{jfc.png}}
\\\\hypersetup{pdfpagemode = FullScreen} \\\\begin{document} \\\\begin{frame} \\\\transduration{9} \\\\titlepage \\\\sound[autostart,encoding=ALaw,inlinesound,bitspersample=16,channels=2,samplingrate=44100]{}{Intro1.wav}
\\\\end{frame}
\\\\end{document}
On a RedHat Enterprise 6 I can generate a pdf file by pdflatex foo.tex. I obtain a pdf file including sound all is perfect. 
Now I would like to do the same with MikTeX and the same files. With TeXworks I choose pdflatex composition and the pdf is generate but I have no sound. According to pdf file size it seems that the sound tracks are in the pdf.
The file Intro1.wav is exactly the same on windows and linux what's wrong. I don't understand what happen.
Any body have an Idea
Regards
J-F Challe
