[2.1.13] Visualizer does not work ?!

Hi All,

I’m working on a Virtual machine.
I tried to follow this tuto : here but I can’t see the light in visualizer.
I tried also with lyrics and chords, and nothing displayed in Audience view.
New version and new project.
Could it be caused by the fact that I use a virtual machine ?

Maybe it is the same issue I have with automation that does not work at all… (I mean the virtual machine)

Does it work with the “real” machine?
