All electronic devices making strange crackling buzzing noise (on different volumes) everywhere in house.

It's not the problem of the outlet, as I took the speakers into the bathroom, and it makes the same noise.

I listened to the computer power supply and the laptop brick too. It seems the loudness of the depends on the load on the power supplies.

Forgot the record but light bulbs are NOT flickering, only AC/DC devices are noisy.

There are NO signs of overheating and electric smell YET.
