SDL + QTKit: Possible to use together?

I've got what should hopefully be a simple programming question: Is it possible to use the SDL (Simple DirectMedia Layer) library together with QTKit, to play back audio only? Obviously, video playback with QTKit and SDL isn't going to work - which is fortunate as that's not why I'd be using QTKit.

If that option isn't possible, then is there a C or C++ or Objective-C library I can use to play compressed audio in the HE-AAC format, that will compile on the Mac? I don't mind having to compile things from source code, but I'd rather not make end users of my software have to do the same just to use it.
