Adding callback procs to SimplePlayThru

Hi,

I'm trying to add input and output callback procs to SimplePlayThru. I added the code below to the end of SetupAUHAL(). The input proc is being called but not the output proc.

What I'm missing?

thanks
Jeff

AURenderCallbackStruct input;

input.inputProc = InputProc;
input.inputProcRefCon = 0;

err = AudioUnitSetProperty(HALUnit,
                   kAudioOutputUnitProperty_SetInputCallback,
                   kAudioUnitScope_Global,
                   0,
                   &input,
                   sizeof(input));

input.inputProc = OutputProc;
err = AudioUnitSetProperty(HALUnit,
                   kAudioUnitProperty_SetRenderCallback,
                   kAudioUnitScope_Input,
                   0,
                   &input,
                   sizeof(input));
