I moved the project into a new file and now the damn metronome sound is gone. So basically if I solo the piano audio track the metronome sound can be heard, but I mute the audio track it disappears. If I solo the other tracks the sound is also gone, it only can be heard as long as the pain audio track is not muted. Everything was a few ays ago until I opened the project today and everything was just all messed up.
