VLC two audio channel Visual Studio 2010 c#

[romero124]

Hello,
I am programming a project in Visual Studio 2010 C# using axVLCPlugin to play a .mp4 video which has two audio channels, first one contains english language and the second one spanish.

Now, I am trying to build a button to change the language once pushed, but I don't know how to do it.

Thank you in advance
