COM Objects > CoreAudioDevices object > Methods > CoreAudioDevices.RenderPartMuteGet method

Remarks

Obtains the muting state of the stream leaving the render part of the given audio endpoint device. The muting state can be modified through the CoreAudioDevices.RenderPartMuteSe t method.

This method is only intended for usage with Windows Vista and later versions: further information about management of audio devices in Windows Vista and later versions can be found inside the How to access settings of audio devices in Windows Vista and later versions tutorial.

For further details about methods related to the management of core audio devices refer to the CoreAudioDevices COM object.

Parameter

Description

nDeviceIndex

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

nPartId

Identifier of the render part.

Supported values are the following:

Mnemonic Value	Value	Meaning
