Hi,

According to msdn document, I found Kmixer.sys does mixing and gave back
mixed data stream through IMiniportWaveRTStream
Is there any way to mix it in driver.
I found KSCATEGORY_MIXER in ks.h, what does it really do? Is it the one for
each application stream mixing?
Also I found term hardware mixing. What mixing it refers to?
I am working on virtual driver.

One more thing can we override the volume control of each application like
master/Endpoint volume in driver?

Thanks,
