A few days ago I posted the following question:
I'm trying to get a feel for working with Audio Units. To this end
I've written a small command line program that sets up a minimal
AUGraph consisting of an AUFilePlayer and the default output unit.
Essentially this is a re-implementation of the SimpleSDK PlayFile
program, but in a way that actually makes sense (if I say so
myself), using just C API.
My simple command line tool works fine and plays audio files if I
compile it as a C++ or Objective-C++ program. However, when I try
it as a regular C or Objective-C it will compile and link just
fine, but the call to AUGraphOpen() will return with an error -2005
(badComponentType).
It seems that this behavior is _reversed_ for Debug builds. (zerolink
is turned off)
Furthermore, when I try the code from a Cocoa program, I always get
that error, no matter how I compile the code. It seems I'm
overlooking something obvious, but I don't know what...
I would be grateful if someone could comment on this, and maybe have
a look through my simple source code, which can be found here:

I really need a push in the right direction...
