As I read it, the MSVadSimple driver should support 6-channel and 8-channel 
audio.  If you install that driver, does the Speaker Configuration wizard work?

Ok, when I added 16 bit as valid, it all started working. Kind of. It seems 
that in order for the audio CPL device properties and config to work properly, 
it REQUIRES that 44100/2/16 be supported, if not: no speaker config, and the 
device advanced tab is missing (!)

Why does Vista not care about what KSDATARANGE the device is reporting ? I have 
one case where my device supports 48000 KHz ONLY, and after I refuse 44100/2/16 
format, PropertyHandlerProposedFormat stops being called (!), resulting in a 
non-usable device!

The form factor of my device is KSNODETYPE_SPEAKERS

This ain't funny anymore  :(
