As soon as I let my laptop charge and stream or listen to myself, there's a humming sound. But if the charging cable is not connected, everything is fine. How so?
I type hum loop over grounding.
Make a try by turning the charger's plug by 180 degrees
This is due to the current flowing into your laptop and its frequency. If you stream via ps4 and the controller is charging you can also hear a noise
Krass It just works, thank you
Pretty sure coming from the ground. You have to stick electrical tape in the middle of the connector, then it stops. It is best to get a sheath flow filter.
Here you have more detailed information:

Already fits. Cable just had to be turned a bit.
Noise as soon as the charging cable is connected to the laptop - why?
a) You have to turn the plug (especially if the audio input source is grounded)
b) Possibly a cheap power adapter bought extra or a fake / knockof
That happens frequently
