Problems with output

Hi. I have this problem with Windows Cubase 10.5 on some songs. the meters on the individual tracks are working, but there is no meter response on the main output, therefore no sound. This happens only on some songs. I have tried to figure it out, all seem to be ok with the sound card, Focusrite 2i2, 3rd gen., studio setup and audio connections, so, any idea what to look for?



Could you attach your MixConsole screenshot, where we could see the routing, please?

Re-assign the track outputs to the Master out.
