Apple's stereo mixer currently does not implement panning for stereo inputs
(only mono inputs). This may change in the future since there are several
interpretations for this type of panning.
When you're using the 3D mixer are you making sure that the scope you're
using is kAudioUnitScope_Input (instead of global)?? Have a look at the
AUMixer3DTest sample code. It should point you in the right direction.

When I'm using the stereo mixer (my input is a WAV file with
2-channel 16-bit linear signed integer PCM data, again), I can
affect the volume (kStereoMixerParam_Volume), but the panning
(kStereoMixerParam_Pan) has no effect whatsoever. Someone has
suggested to me that pan is meaningless when the input data is
stereo, but seeing as how the default input of the stereo mixer is
2-channel, I'm more than a bit confused here.
When using the 3D mixer, I can't set ANY parameters.
k3DMixerParam_Azimuth, k3DMixerParam_Elevation, they all return
kAudioUnitErr_InvalidParameter no matter what I do.
These are all V2 AudioUnits (to try it with V1 I'd have to rewrite
this whole thing all over again and I refuse to do that unless I
have to).
