Problem now solved. The problem problem came from i returned NTSTATUS STATUS_SUCCESS with no byte returned in ioctl function : IRP_MJ_QUERY_VOLUME_INFORMATION->FileFsMaximumInformation. But I have the impression that this windows player requires oplocks functions, I try to disable oplocks function then the player (Music) does not work. And I do not control evil Oplocks functions. PROBLEM SOLVED !

They are not evil and fortunately not yours to control. The oplock protocol is implemented in the FsRtl library and NTFS and other file systems just use this lib to support oplocks. All you need to do now is not break them and do I/O without deadlocking the system. How ? Read the oplock semantics paper or doc from Microsoft.
