AudioConverterNew() and 'perm' error on iPhone

I'm trying to playback a mp3 file on an iPhone and when creating a converter using AudioConverterNew() it always returns error 0x70657256d ('perm'), same for m4a and 'alac' files but works fine for 'lpcm' (aiff) files.

When running in the simulator all file types works OK.

When using the AudioQueue API everything also works OK.

Isn't it possible to decode non pcm files on the iPhone?

I need to get access to the decoded audio data for further DSP processing so I can't use the AudioQueue API. Or is it possible to do this using the AudioQueue API?

Thanks,
Rolf
