Yes, with the caveats that not all devices have volume controls and that even the ones that do might have them in different locations (master vs. left/right for example).

AMS and the Prefs Panel talk directly to the HAL in order to control

sample code (/Developer/Examples/CoreAudio/HAL/HALLab).
So if I'm following you, I should be using my reference to the hardware input device (kAudioHardwarePropertyDefaultInputDevice), and modifying its volume properties to do what I need? Thanks.
