Alarming noise at cold engine

Hey!
I have this weird sound that only happens when the car is cold, on D or P gearbox and at the idling RPM like 900. Once you move or get the revs above its all good again. Sounds like a demon is going to be born

All I hear is normal injector noise. Must be a very small demon.

Hehe yes injectors are audible but if you hear in the background of injectors there's this bass grinding sound.
