First of all, I’m just furious at the moment, I’ve been working on a project and started to sound good. I’ve unplugged my speakers and plugged in my headphones. Guess what? The sound is gone. There is a visible signal, if I render the project the file is fine. Even if I add a new audio file or instrument to the project those have sound. Everything else before is completely silent.
I have no idea how to fix it.
