Dominic, when you are getting the parameter value are you currently
rendering and
supplying input sample frames which are non-zero? The parameter value is meant
to give a measurement on the power of the input you're giving to the mixer.

Hello. I am trying to get kStereoMixerParam_PreAveragePower from a
stereo mixer.
I'm doing the following:
mLeftLevel = 0.0;
error = AudioUnitGetParameter(mixerUnit,
kStereoMixerParam_PreAveragePower + 0,
kAudioUnitScope_Input,
0,
&mLeftLevel);
Every time this runs I mLeftLevel comes back as -120.0.
AudioUnitGetParameter isn't returning an error. Any idea? Perhaps
I don't understand something.
