Speakers Make Buzzing Noise When Plugged In. My laptop is making a whinnying noise when power cord is plugged in. I have also tried plugging the speakers into a separate outlet.
In a nutshell, a ground loop results from a clash of different ground potentials of AC sources or equipment, and this brings. It is often easiest to perform this repair. The buzzing noise is always there regardless of whether I'm listening through speakers plugged into the back of the motherboard or using headphones connected to the green port at the front of my case.
If you have two prongs, just flip it upside down.
Removing the charge kills the noise and makes the sound crystal clear again.
My speakers and laptop were plugged into the same outlet, so I tried switching the outlet for the speakers. the buzzing was still there. This can be particularly pronounced when the video is queued up to play, but hasn't started playing yet. If the buzzing noise is still audible, you can check your hardware for issues.
