In QuickTime 7 we do not use the Sound Manager to play audio, so 'sdev' components will not help you. If you just want to get at the audio data of a movie as PCM, your best bet is to use the MovieAudioExtraction API's. See Movies.h in the QuickTime 7 SDK for Windows. This suite of API's will let you pull PCM data from a movie and do whatever you like with it.

If you want to direct audio from a movie to a DirectSound playback device other than the default Windows one, you'll need to use the:

QTAudioContextCreateForDevice() + SetMovieAudioContext() calls. Again, see Movies.h.

    Hello,
thanks for your answer. Platform is MS Windows. QuickTime: 4 and 7 (latest).
   More general, I'm trying to forward all sounds from QuickTime to
special output device which gives me sound samples. If I can use more
simple and consistent approach please advice.
    Thank you again.
     Andrey.

What platform are you running?  What version of QuickTime are you
running?  The answer to the question depends on the answer to those
two questions.

   Hello everybody,
I want to change QuickTime output device in run time. Please let me know how can I do this? I managed to enumerate audio output components with FindNextComponent function and specifying kSoundOutputDeviceType as a componentType. Now I want to select component as output for QuickTime. Is it possbile?
