Parameter

Description

nDataFlow

Direction in which audio data flows between an audio endpoint device and an application.

Supported values are the following:

Mnemonic Value	Value	Meaning
DEVICE_DATA_FLOW_RENDER	0	Audio rendering stream. Audio data flows from the application to the audio endpoint device, which renders the stream
DEVICE_DATA_FLOW_CAPTURE	1	Audio capture stream. Audio data flows from the audio endpoint device that captures the stream, to the application.

nDeviceIndex

Zero-based index of the audio endpoint device. The total number of render or capture audio endpoint devices can be obtained through the CoreAudioDevices.CountGet method passing DEVICE_DATA_FLOW_RENDER or DEVICE_DATA_FLOW_CAPTURE to the nDataFlow parameter.

nPartIndex

Zero-based index of the requested subpart. The total number of available subparts can be obtained through the CoreAudioDevices.PartsCountGet method.

Return value

Value	Meaning

Empty string	An error occurred or information not available, check the LastError property value in order to get the error code
Valid string	The requested friendly name
