I have cheked that several times. They are visible & so are the monitor Icons.
I even copied one sound track and pasted it on one that was free but nada, no sound.
The strange thing is that the speaker-icons of both tracks are hollow. Normally they are filled white. But they do toggle on (visible) & off(invisible) when clicked on.
When visible, the sound should play in normal circumstances.
Why do they appear hollow – outlined? Do you have any clue?
The tracks that are free have the Icons filled white. But I wonder IF it matters, as long as they are visible (i.e. in ON position)
I must have done sth. But the Question is, “What?”.
I shall continue tomorrow.
