Control left & right speaker balance level on Windows 10 using C#

I need to control the left & right speaker balance level on Windows 10 using my C# application.

I was able to control the master volume level of speaker and microphone using Windows IAudioEndpointVolume interface through the Audio Manager C# wrapper which is also mentioned in http://stackoverflow.com/questions/14306048/controling-volume-mixer.

But still, I'm unable to control the L/R balance. Is there any specific interface or property I should use?

I'm building Console Application using Windows 10 SDK & .NET 4.6.1 framework through Visual Studio 15
