C# soundplayer doesn't work in Win7 and Vista

In c#+VS2008+XP, I can play a wav file by calling

System.Media.SoundPlayer sp = new System.Media.SoundPlayer(new FileInfo( newfile).FullName); 

sp.Play();//sp.PlaySync();


In year 2010 when I test it in Win7 and vista, I found it doesn't work at all(no sound from speaker and no exception from program).

However there is no problem when I play back this file in any players or in c++ Directshow and c++ soundplay();

Do anyone know how to solve this C# SoundPlayer problem?

Thanks in advanced
