In the TestAudioPlay.class file, that should be:

Public Sub Form_Open()  ' Not TestAudioPlay_Open()
   audio = New Channel As "audio"
End

The TestAudioPlay form does not know its own name. It just knows it is a Form. A form's name is for the benefit of classes and 
modules external to that form. It allows us to call Public methods, and access Public properties, of distinct classes/modules. 
This is how we can call FMain.Close from TestAudioPlay.

When designing/editing a form in the GUI editor, you can right-click on an object and then bring the mouse cursor over "Event" 
in the pop-up context-sensitive menu. That will show a list of the events that particular object raises. When you select a 
certain event, you will get an empty event handler subroutine in the form's class file/tab.
