Hello, my driver is a virtual sound driver based on WaveCyclic. It worked
fine on Windows 8, but during WHCK KsPosition test, the test fails with the
following error message.
Message12/6/2013 2:10:26.125 PMFailed to query for basic support
KSPROPERTY_AUDIOSIGNALPROCESSING_MODES: Last error:1170
Can I add support for IMiniportAudioSignalProcessing in WaveCyclic based
audio driver?
I've noticed that the new WDK sample SysVad
support IMiniportAudioSignalProcessing property. But it was based on
WaveRT.
Or should I change my project to WaveRT based example? Does WaveRT works
for virtual sound driver? (We don't have the codec hardware, just to
capture the pcm audio data and send out to another stack.)
Thank you!
