Problem with Windows XP and Seven(Vista ..)?

Hey there, I've got a little problem with my OS. In fact I use ASIO Driver for making music with a certain DAW ! Under Windows XP I could use and ASIO and my SoundMax HD (SRS SoundBox filter activated) drivers. But on Vista and Seven I can't ! This is bad for me if I want to preview the result of my mix in any audio player as VLV or Itunes. I must be terminate the DAW before hearing the result in an audio player
