Though it isn't documented anywhere, the only time I've gotten this return value is if you are calling on something that isn't actually an audio unit. Check the value of au. Be sure you have actually opened the AU correctly.

I have been trying to set a AUHAL's output device to something other than
the default output. Here's the code I've been using:
error = AudioUnitSetProperty(au, kAudioOutputUnitProperty_CurrentDevice,
kAudioUnitScope_Global, 0, &deviceID, sizeof(UInt32));
At first I though I was getting the error because I was trying to set this
property after I had initialized and started the graph, but once I moved the
function to before the init graph I got the same error. I looked through
the archives and couldn't find anyone else with this error code with
kAudioOutputUnitProperty_CurrentDevice.
Any help is much appreciated.
Thanks
