The Computer Audio Device Change messages will not be sent without a call to Bind.

Line 34 in setting\_service\_dotnet\_wrap.cpp should look like this:

```auto
	IAudioSettingContextDotNetWrap^ CSettingServiceDotNetWrap::GetAudioSettings()
	{
		if (CAudioSettingContextDotNetWrap::Instance)
		{
			CAudioSettingContextDotNetWrap::Instance->BindEvent();
		}

		return CAudioSettingContextDotNetWrap::Instance;
	}

```

Then the callbacks start working.
