Classes > CoreAudioDevicesMan class > Methods > CoreAudioDevices.RenderPartMuteSet method

Remarks

Applies the muting state of the stream leaving the render part of the given audio endpoint device. The current muting state can be obtained through the CoreAudioDevices.RenderPartMuteGet 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 CoreAudioDevicesMan class.

Syntax

[Visual Basic]

[C#]

public enumErrorCodes RenderPartMuteSet (

Int16 nDeviceIndex,

enumCoreAudioRenderParts nPartId,

bool bMute

);

[C++]

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
RENDER_PART_CD_AUDIO	0	CD Audio
