Usage Summary Table

Yes Yes Pin KSPROPERTY DWORD

The property value (operation data) is a DWORD that represents the current output mode of the audio decoder.

Remarks

The property value can be one of the following mode constants defined in the header file ksmedia.h:

KSAUDDECOUTMODE_STEREO_ANALOG
Indicates that the output is in analog stereo.

KSAUDDECOUTMODE_PCM_51
Indicates that the output is in PCM 5.1 channel digital.

KSAUDDECOUTMODE_SPDIFF
Indicates that the output is SPDIFF format AC3 digital.

The audio miniport driver get-property handler returns the current mode of the decoder, whereas the audio miniport driver set-property handler requests that the decoder switch the output audio format to the requested mode.

We recommend that you specify a default value for the KSPROPERTY_AUDDECOUT_CUR_MODE property in the minidriver's serialized property set in the registry.

For more information, see Audio Miniport Drivers.
