Meters moving in record mode with no input

2.3.3 version

My record meters are moving and nothing is plugged in to the laptop.
When I do plug in my RODE interface the meters keep moving with no
microphone attached. Any clues?
I am a novice, but this problem just started after making some great recordings.

I’d guess that it’s picking up noise from the laptop’s built in microphone.

By Jove… that was it!
