Let me try to clarify my bleary eyed at 4am in the morning questions.

...
iOS 4.3 returns:

Sample Rate:              44100
 Format ID:           1819304813 (lpcm)
 Format Flags:              3084
 Bytes per Packet:             8
 Frames per Packet:            1
 Bytes per Frame:              8
 Channels per Frame:           2
 Bits per Channel:            32
------------------------------------
Seems that this a remoteIO output format change, from the standpoint at which the rio allows access???(since, obviously the output hardware converter format is still what it was before...)

So, is capturing the output of remoteIO at the end of an augraph no longer allowed in iOS 4.3?

Or Is there a bug in the underlying audioconverter for ExtAudioFileCreate in 4.3 in this particular scenario ?

I mean, shouldn't the call to ExtAudioFileCreate (with the correct file destination format ASBD) automatically add an audioconverter to deinterleave,etc.. anyway ?

Could anyone from the coreaudio team offer any advice/insight? 

Many Thanks
