Hello,
Although I've seen a lot of people reporting static noise from the speakers, I never had a problem with mine until the last big update (Windows 10 - Version 1607). It started right after the update's restart.
I've ran dell's diagnostic tool; nothing wrong.
The noise is there even when I disable the speakers.
