The SupportHandler is the field you marked with a comment "No raw serialization
hander" in your example.

Hi
Thanks for the response. I have already provided my own support handler i.e
AudioVolumeLevel. If you please elaborate a bit, would help
Thanks

The only way I have been able to get this to work is to provide my own
SupportHandler. I would be very interested to hear about other solutions.

Subject: [wdmaudiodev] Audio driver : KS topology test fails
DTM test KS Topology Test fails with our driver. Following is the error
====

IOCTL called with an output buffer size of 1.

KSPROPERTY_MEMBER_FLAG_BASICSUPPORT_MULTICHANNEL set and must return the number
of channels in KSPROPERTY_MEMBERSHEADER.MembersCount

We set the no of channels to 2, but still we are facing this problem.
DEFINE_KSPROPERTY_TABLE (gVolumeProperties)

};
KSPROPERTY_VALUES VolumeValues =

},
SIZEOF_ARRAY (VolumeMembersList),
VolumeMembersList
};
KSPROPERTY_MEMBERSLIST VolumeMembersList [] =

KSPROPERTY_MEMBER_STEPPEDRANGES, //MembersFlags
sizeof (VolumeRangeAndStep[0]), //MembersSize
2, //MembersCount
KSPROPERTY_MEMBER_FLAG_BASICSUPPORT_MULTICHANNEL //Flags
},

},
{
{
KSPROPERTY_MEMBER_VALUES,
sizeof (VolumeDefault),
2,
KSPROPERTY_MEMBER_FLAG_DEFAULT
},
(PVOID) &VolumeDefault,
}
};
Any pointers on how to proceed futher would help.
Thanks
