Return Value
A KSPROPERTY_AUDIO_SAMPLING_RATE property request returns STATUS_SUCCESS to indicate that it has completed successfully. Otherwise, the request returns an appropriate error status code.
Remarks
The miniport driver should return an error on a set-property request if the node does not support the specified sampling rate.
This property is used to control the sampling rate for the following node types:
ADC node (KSNODETYPE_ADC)
DAC node (KSNODETYPE_DAC)
SRC node (KSNODETYPE_SRC)
