Can you send a screenshot of your wave and topology filters in KS Studio, with
"show nodes" in effect? I'm interested to see whether you have a
KSNODETYPE_VOLUME node, and if so, what the ranges are.

Subject: [wdmaudiodev] WASAPI endpoint volume callback
Dear all,
I've implemented my VAD based on the old WaveCyclic MSVAD code and when I
register for volume callbacks via IAudioEndpointVolumeCallback mechanism, I get
NO callbacks for my VAD device, but I DO get callbacks for other audio
endpoints.
So I must be doing something wrong in the driver obviously.. Tips on what I
should check in the code ? I have the hw.h/hw.cpp with CMSVADHW class
(GetMixerVolume/SetMixerVolume etc.).
Regards
/Robert
