stereo in meter activity

I have cubase 10.5 pro and there is an annoying issue that I cant resolve. I create a new , completely empty project and I have visible meter activity on the stereo in meter. Nothing is playing/sounding yet the meter is moving up and down slightly. I cant hear a sound, even on headphones, so what could it be ? I have a Komplete Audio 6 sound interface (first version). Ive tried disconnecting any instruments connected to the sound inputs, it makes no difference. There is sound input from somewhere but I cant see where. Anyone got any ideas ?


As far as I can see, the signal is on the Input Channel. You don’t have Audio track created yet, so you can’t hear the signal. Add an Audio track, route it to your output and enable Monitor. Then you can hear what kind of signal is it.
