Sorry, but I don’t follow what you’re trying to do. Can you elaborate? Maybe
draw some audio flow diagrams?

lets forget about kmixer.sys.
What about KSCATEGORY_MIXER ? Can it be used for getting separate application
stream and later mix on my own?
Or, is there any other way ?

Whatever MSDN document you found should be removed; kmixer.sys hasn’t existed
since Windows XP.

Subject: [wdmaudiodev] Mixing applications audio stream in driver
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?
