je up car j'ai trouvé la solution après avoir essayé beaucoup de choses
je cite :
"Download http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=6812 Go to C:\\Program Files (x86)\\Microsoft DirectX SDK (June 2010)\\Utilities\\bin\\ chose the folder of your OS, x64 or x84 and then start dxcpl.exe Go to Audio and then turn the DirecSound Debug Level to More & Use Debug Engine. Ok, the game can start now. Good look
"
Dans mon cas ça a marché
