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
