Hi,
Right now, I am only listing KS_CATEGORY_CAPTURE and KS_CATEGORY_RENDER.
I expect that I should list KSCATEGORY_AUDIO as I do for my WavePCI drivers.
But, in the WavePCI drivers, I use "InstallSubDevice( ...., "Wave", .... );"
to link the name in the INF to my kernel mode device.
But, in AVStream I don't see the equivalent function InstallSubDevice().

What categories are you listing for your filter?
