There are properties for the StreamDescription - use that instead.... Daisy has examples of how this is used.

The reason this was removed is that some devices support multiple configurations of sample rate/n channels including a different set of channels at the same sample rate - so you have to be more explicit about what state you really want the driver to be put in...

Ok I know this question is late.

kAudioDevicePropertyRateScalar and the potential to set the audio device's sampling rate via CoreAudio vanished several releases ago.

Is there another way to set an audio device's sampling rate (given that it is variable) through CoreAudio, or are users (and developers) to rely on third party audio control panels and perhaps Apple's own System Preferences panels (which, in MacOS X.1, cannot yet set the audio device sampling rate (unlike MacOS 9.x)).
