Needless to say, a lot of things would be broken if AudioDeviceGetProperty() was broken. So, something else is clearly afoot here.
I'm not sure what your log is trying to show. You say that it "is no longer able to obtain the audio device list". But the output of the log would disagree as that looks very much like the device list. It seems that the errors in your program revolve more around the Component Manager failing to do something.
The evidence here tends to support a corrupt system install. You might try re-applying the latest combo updater by hand or even a clean system install. If you are developing AudioUnits, you might also want to make sure that you don't have any dangling symlinks or aliases in any of the various Components folders too.
