  • Thread-topic: kAudioUnitErr_InvalidElement

I'm calling an AUAudioUnit's renderblock and it's returning "kAudioUnitErr_InvalidElement".
Neither Google nor the CoreAudio documentation is clear on what this error means.

Here's the offending call; parameters are simply passed through verbatim from what the system passed to me through the audio render callback.

OSStatus err = myAURenderBlock( actionFlags, timestamp, frameCount, outputBusNumber, ioData, nil );
// err returns as kAudioUnitErr_InvalidElement

Anyone knows what kAudioUnitErr_InvalidElement can mean in this context?
