    I want to access the playback devices->Speakers->properties->levels
    tab -> (microphone, front mic, linein etc)

    I want to access these and change their respective volume levels

    I have enumerated the rendering devices and I get the number of
    playback devices, but I want to access the cub components of the
    selceted playback device.

    I have accessed the property store but i could only get the name of
    playback device. I could not move further.
    I also tried IPart and IPartlist but i got again the incoming and
    outgoing devices.
    I tried IAudioRenderClient but could not meet success.

    I would like to know which functions and API's I need to use and in
    which order thay need to be used, so that there volume could be
    changed through vc++ code
