Wouldn't there also be errors in the AudioDeviceAddIOProc/AudioDeviceStart/AudioDeviceRemoveIOProc functions as well? The device does start properly and even gives me consistent data as I would expect. It only tells me I have an error as soon as I stop it.

The usual reason for getting that error from AudioDeviceStop is that you are trying to stop an IOProc that hasn't been registered with the device yet.

I get a kAudioHardwareIllegalOperationError in my AudioDeviceStop function.

What does this actually mean? My app was working fine, then I start getting this message, but I have no idea what change is causing the error. The CoreAudio docs say nothing about this problem... Please help me understand the cause of this error. Thanks in advance...
