When I start up Cubase and open a project and play it, sometimes there is sound, and sometimes there isn’t. It’s entirely arbitrary. I never change anything about the sound settings of either Cubase or the project (or for that matter, anything else in Cubase or the project). When there is no sound, I have to start up Cubase multiple times until suddenly … there is sound. When eventually there is sound, it sounds perfect.
There’s nothing wrong with the sound system of my PC or Windows, as none of the dozens of other applications on my PC never ever has any sound problem. What’s going on?
