Sometimes I open up a session and I see levels but I hear nothing.
I open another template and it’s fine. then go back to the one that was silent and some times it’s fine and other times it requires a quit to be heard.
Switching drivers in device setup and then switching back does not do anything. Only closing the template and then reopening it or rebooting Cubase.
I have a similar issue however in my case I often loose all recorded audio sound suddenly when a project has been open for hours. So no meter signal , no sound, it’s sudden, as if cubase can’t read the audio clips. A reboot of PC always cures the problem. Just closing and restarting cubase will not bring the audio back.
