Does no response mean nobody knows?
Does anyone know where Sounds and Audio Devices properties stores the
current Speaker Configuration in the registry?
Thank you,

Subject: [wdmaudiodev] KSPROPERTY_AUDIO_CHANNEL_CONFIG and
KSPROPERTY_TYPE_GET
Hello,
I would like my KSPROPERTY_AUDIO_CHANNEL_CONFIG property handler to
support KSPROPERTY_TYPE_GET so that I can allow the user to change the
channel config from within my Mixer window (which is much easier to get
to than the control panel > sounds and audio devices).
When I enable the GET verb, KsStudio crashes with a GPF - and it seems
that control panel > sounds and audio devices doesn't ever try to read
the KSPROPERTY_AUDIO_CHANNEL_CONFIG. In other words, if I change the
channel config manually with my mixer window, the change isn't reflected
in control panel > sounds and audio devices (it just displays whatever
was set there the last time - so it seems it has its own private variable
stored somewhere).
Is it possible to get the control panel > sounds and audio devices to
read the KSPROPERTY_AUDIO_CHANNEL_CONFIG from my driver?
Should I file a bug report about KsStudio crashing...? :-)
Thank you,
David A. Hoatson
