What interfaces do I need to call before I can use IBasicAudio to control volume?
I tried using Audio Renderer's IBasicAudio methods to control the volume of a mic. The putVolume() return S_OK but the volume of the mic remains the same.
What interfaces and methods do I need to use in order to control the mic specifically?
Would appreciate any help. Thank you.

putVolume() only changes the output volume of the wave or directshow audio renderer, it does not change the volume level of a microphone input.
