I went through something similar many years ago and found I had to include
property handlers for KSPROPERTY_AUDIO_CHANNEL_CONFIG and
KSPROPERTY_AUDIO_STEREO_SPEAKER_GEOMETRY in the miniport's DAC node
(KSNODETYPE_DAC).
Thnx Jeff, I'll try that out. However, I finally got WMP to open my device in
5.1 mode, by ehm... configuring my device in sound panel for 5.1 surround
mode (blush). But if I'm not implementing KSPROPERTY_AUDIO_CHANNEL_CONFIG, how
come Sound panel seems to be able to get/set that configuration anyway?
Is it PortCls that implements it ?
My VAD's configuration should mirror the configuration of my target sound
device so I'd need to change the configuration programmatically, will I still
need to implement those handlers, or can I make use of what PortCls provides ?
