Ok, I read
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/stream/
hh/stream/pcdesign_4s9z.asp ... but it doesn't tell how to set a default
volume via a driver INF file. If I do a registry diff of the registry
before and after changing the volume via the mixer slider, I can see
that the setting is stored in HKR,,Mixer\2\Controls\0 in the Channel0
and Channel1 values. If I set those values explicitly via my inf - it
doesn't seem to work, the mixer doesn't setup his device parameters
until I manually go in and change a volume. Is there a secret way to set
a default volume of a device in an INF file?

Thanks,
-Chris
