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?
