No - As Robert stated, he's doing this just fine.
I think the key difference here is that Robert is gluing the 2nd AUHAL
into the AUGraph (because you can only have one output unit in an
AUGraph). Since Chilton is not using AUGraph, he is simply using the
connection properties to paste the AUs together via the
kAudioUnitProperty_MakeConnection property. Thus OutputUnit pulls from
FilterUnit pulls from InputUnit (where InputUnit & OutputUnit are both
AUHAL units and FilterUnit is an effect unit). This specific
configuration doesn't appear to work. The same exact code works just
fine if you have the OutputUnit pull from the FilterUnit pull from the
OutputUnit. Somehow this seems like a bug to me.
If you need more information then maybe Chilton can probably post some
source code.
We're working up an extension to the existing sample code and will have
that available as soon as we can.
Great!
