Since about two month, my headphones connected using a USB-C → Jack have a small white/static noise in the background, only when the screen is turned on.
More exactly, it stops a second after the screen turns black when I press the lock button, and it starts again as soon as I press the lock button again.
If I listen or don’t listen to something doesn’t change the white background noise. I tried two different USB-C → Jack adapters. I didn’t have this issue before December.
Does anyone have the same issue, and is there a fix?
