Hi all:
Does any one know how to add KSATTRIBUTE support by use WaveCyclic. I fill
Flags field with KSDATARANGE_ATTRIBUTES. And append KSATTRIBUTE after
KSDATARANGE_AUDIO. The driver can load correctly. But when start to capture
audio, I got BSOD and dead in KS.sys. When modify my code to use WaveRT,
capture audio can run correctly with out BSOD.
Does this is bug in portcls or WaveCyclic can not support KSATTRIBUTE?
BR,
Tzung-Dar Tsai
