Access to vista component devices of playback devices likemicrophone, linein, front mic etc in vc++
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 |
