kAudioQueueErr_InvalidCodecAccess (-66672) when using ExtAudioFile on iOS 4.2

kAudioQueueErr_InvalidCodecAccess (-66672) when using ExtAudioFile on iOS 4.2

On the final line of the code below, I am getting the error kAudioQueueErr_InvalidCodecAccess. I know this code worked in previous sdks, though I am not sure which ones exactly.

I am running on an iPod Touch 3G (MC008LL), with iOS 4.2.1.

I am building with SDK 4.2 for deployment target 3.2.


The docs describe this error as "The codec could not be accessed.". Not very helpful IMO. I have seen this code fail when the hardware is in use (error: hwiu), but this is the first ive seen the current error.

Anyone have any insight into what causes this error? Any help you can give is much appreciated.

Thanks,

Doug
