Hi Dan,
I am not experienced either. As I understand, in order to do file read and write, we need to let the file i/o API that we are using know the data format of this file.

Ahh, it works now. Thank you.
I'm still a bit new to Core Audio though. Can you give me an explanation as to what this property is and why it needs to be set?

I had the same problem before. Try set the kExtAudioFileProperty_ClientDataFormat property before the ExtAudioFileSeek line.
ExtAudioFileSetProperty(audiofile, kExtAudioFileProperty_ClientDataFormat, sizeof(audioFormat), &audioFormat);
ExtAudioFileSeek(audiofile, 0);

For some reason, seeking by even 1 frame with ExtAudioFileSeek is resulting in an OSStatus of
-66568, a code that I cannot find any documentation for. The ExtAudioFileRef is setup properly and I can read from it just fine, seeking seems to be my big issue here.
