如何以编程方式更改Windows音频设备的友好名称？

Question

What is the proper API call that I should use to rename an audio device on windows? My goal is to change the device name that is shown to the user when they right click the volume icon and select "playback devices." I believe "friendly name" is the property I want to alter.

I've managed to successfully call SetupDiSetDeviceProperty , which returns true. If I subsequently call SetupDiGetDeviceProperty , the recently set value is returned. However, this value seems to only exist within the context of my application - the system setting seems unchanged.

Is there another function call that I should call instead of or in addition to SetupDiSetDeviceProperty ?

I have been running my application as an administrator, so permissions shouldn't be an issue.

I am not sure if this will allow you to change it, but according to this : (msdn.microsoft.com/en-us/library/windows/desktop/dd316587(v=vs.85).aspx)

PKEY_DeviceInterface_FriendlyName

The PKEY_DeviceInterface_FriendlyName property contains the friendly name of the audio adapter to which the endpoint device is attached (for example, "XYZ Audio Adapter").

The vt member of the PROPVARIANT structure is set to VT_LPWSTR. The pwszVal member of the PROPVARIANT structure points to a null-terminated, wide-character string that contains the friendly name. Requirements
