That code seems kosher, but when I decode the symbols in the crashed
thread you posted, the crash appears to be happening in response to
somebody hitting one of the test buttons in the surround sound editor.
Specifically, it appears to be throwing an exception that isn't being
caught before exiting an ObjC entry point. The exception is being
thrown because AudioDeviceStart is returning some error.
It's possible that this error is due to your driver doing something
that makes it fail to start. But this code I was looking at in AMS is
going to always crash like this when AudioDeviceStart returns an
error. I wrote up a bug about it, for AMS to fix this in general, but
you might want to take a look at why AudioDeviceStart might be
returning an error in this case.

Is there anything special I have to do to use
IOAudioStream::setStreamAvailable?
I have tried surrounding it with the following:
/////
pauseAudioEngine();
beginConfigurationChange();
setStreamAvailable(fEnable);
completeConfigurationChange();
resumeAudioEngine();
/////
