       I am currently working on an audio driver which is based on wave
cyclic port driver. This driver is virtual audio driver. I am having issues
with passing the General Audio Test from the HCK tests. Following are the
two failures I am facing :


Start Case: ID 16.200:300.1.3 : KS
no. of channels:
Device Name = XXXXX
PnP ID      = ROOT\MEDIA\0000
    Property SET is not supported
    Property GET is not supported
        Property SET is supported
        DeviceIoControl returned 0xEA
        Error : More data is available.

        required bytes for getting dataformat is 82
        dwDataLength = 82
        required bytes for getting dataformat is 82
        DeviceIoControl Passed when expecting DeviceIoControl to Fail.
            ERROR:Failure information:

Please help me in solving these failures.
In case of the first failure I am not providing any support for
KSPROPERTY_CONNECTION_DATAFORMAT property. Still I am not getting the
reason for this failure.
I am not getting the reason for any of the above failures which would help
me solve these...so please help !!!
