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.
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'.

HI Alexander,
I just answered you on stack exchange, it think there is something wrong with your stream description. There might be more, but you should check that first.
best,
Fokke

I am still unable to write audio samples from my AUHAL's input callback to a file. I have tried a number of things including using the asynchronous version of writing to an audio file in ExtAudioFileServices. Even wrapping the call in a dispatch queue in fear that it was going out of scope. Even though it is probably some small obvious thing that is missing (i'm only a few months into using core audio) I posted a
stack question about it. Apparently other uses have gotten the (-50) error. That is indeed the error I get. (you can run the
GitHub Repo in xcode to verify this). I've been casually trying to get this to work over the past few days and I'm not getting any results. Any idea what I might be doing wrong?
