Thank you for the help. Fokke, I have since changed the way i set the stream for my audio file. You can that in this gist <https://gist.github.com/AlexanderBollbach/3b862db17adf240928f8>.
Christian, I have tried setting that property but since doing that I am now unable to create the audiofile. In fact that might have been the problem to begin with as I was not checking the OSStatus of ExtAudioFileCreateWithURL. I now see that I get a 'fmt?' .. but if you take a look at that Gist I have no idea what could be the reason. In the convenience function CreateInputUnit I get the stream off the audio unit and set it as a member var in my struct. This is what I use to instantiate the ext audiofile but it doesn't seem to like the stream/'fmt'.
