Turns out that all I had to do was to declare the userData struct as a iVar in the header file. Rookie mistake... I've never had to wrap plain C code up in Objective-c before :-)
Thanks for all the responses!!!

Thanks, but this is just regular cocoa for osx, not iOS. And the only thing in my nib is a IKImageView, which is just there so I don't have a blank window. Maybe I should try putting it all together again in a new Xcode project...

This is a long shot.
I had a similar problem and it was unrelated to the setup of the Audio Queue. I had an
AVAssetReader to source sourcing video frames, and I think the act of using these AVFoundation
classes meant that iOS thought "Oh, the iPod has started playing. Let's mute the application audio",
and so the audio stopped and the callback wasn't called again.
Try adding these lines of code to your applicationDidFinishLaunching - they tell iOS that it's ok to
keep the application audio playing while the iPod is playing.
// Registers this class as the delegate of the audio session.
[[AVAudioSession sharedInstance] setDelegate: self];
// The AmbientSound category allows application audio to mix with Media Player
// audio. The category also indicates that application audio should stop playing
// if the Ring/Siilent switch is set to "silent" or the screen locks.
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryAmbient error: nil];
// Activates the audio session.
NSError *activationError = nil;
[[AVAudioSession sharedInstance] setActive: YES error: &activationError];

Subject: Re: AudioQueue run loop newbie question
I tried to NSLog it. Its getting called 3 times when I call it myself, and then the AudioQueue makes exactly 3 callbacks. Probably because I have 3 buffers. If I remove the initial call to the callback function, it is never triggered by anyone...
