The SYSVAD sample is complex with a lot of features you don't need. I
started looking at the old Windows 8 SDK sample MSVAD. It is not a
WaveRT driver but a WaveCyclic but it can give you an idea of what you
need and what you don't. The main thing is to write an
DataRangeIntersection method that forces the format you support..
Yes. SYSVAD has become the exhibition hall for all new features in the
audio stack. I understand there needs to be an exhibition hall like
that, but what MANY developers in the real world really want is just a
simple virtual audio driver to act as a virtual audio cable, without
frills. SYSVAD is 54,000 lines of code spread across 127 source files.
My VAD based on the 8.1 MSVAD sample is 7,000 lines in about 20 files.
The WaveRT vs WaveCyclic thing is irrelevant without hardware.
