iOS 8 ExtAudioFile AppleLossless distortion

I am attempting to narrow down the options why my audiograph code is failing on iOS 8. 

I am using ExtAudioFileRead to extract data from applelossless source files and load structs set up for this purpose.
The buffers and audioData parts of the struct are typed as AudioUnitSampleType.

All of this works as it should on iOS’s up to 7.x. Running on iOS 8.1.2 I can play aiff source files with this code but get distortion if I load the m4a (lossless) files.

What changed in iOS 8 with extaudiofile that would account for this issue?

thanks

rob
