iPhone remoteIO volume

Hello Everybody!

quick question on setting the volume when using remoteIO, why does kHALOutputParam_Volume not get respected?
 I tried doing this:
  status = AudioUnitSetParameter(remoteIOUnit,
                                       kHALOutputParam_Volume,
                                       kAudioUnitScope_Global,
                                       0,
                                       level,
                                       0 );

but it had zero effect, no errors but no results either.

So now I am stuck with either adding in an addition Mixer Unit just to act as a "master volume" or scaling the volume of all the inputs of my "main" mixer, neither seems like an ideal solution.
