Looking at levels on a mixer

Hello everyone.

I'm going insane attempting to get some levels from a mixer (3d mixer in this case).
I can get as far as enabling metering (no error returned), and after that point I initialize the graph, but when I attempt to read using:

err = AudioUnitGetParameter(mMixerUnit, k3DMixerParam_PostAveragePower, kAudioUnitScope_Input, 0, &currentAmps);

I get -2147450879, or badComponentInstance (when I debug).   mMixerUnit still seems to be set to a valid value.

Can anyone give me tips on what situations might cause this?

Regards,
