CFM tricks

I've been working on assembling a little CFM app which uses CoreAudio for the last few days. (We are developing an app which requires OS 9 support, but we'd really like to leverage CoreAudio on OS X. For a variety of reasons, shipping two versions of the same app--even bundled into one package--is not an option for us.)

Anyway, I've tried using CFBundleGetBundleWithIdentifier and CFBundleGetFunctionPointerForName to import all the symbols needed by our app, but I'm getting mixed results. When I import from "com.apple.audio.CoreAudio", everything works great. But calling CFBundleGetBundleWithIdentifier with "com.apple.audio.units.AudioUnit" or "com.apple.audio.toolbox.AudioToolbox" returns NULL, even though that's what's in the CFBundleIdentifier tag of those Frameworks' Info.plist.

Does anyone know what's going on here, or how I could work around this? Any assistance would be appreciated.
