Okay, so you have now an output port; that’s good news. Now, don’t try with an old project. We have an known issue, that if a project once ran into a setup with no output ports, you will not get it to sound again, even if later ports reappear. So instead please create a new test project and try if that now sounds. I have strong believe that it will.
If with the new project you have sound again, but not with older projects, you can send them to me, and I will do some “magic” to them so that they will also do again.
