Issues with audio

Hello,

From time to time the audio is like a light buzz even with muted audio or disabled audio device in system properties. It’s like electricity coming to the speakers.

Any idea? hardware/mount issue?

First thing that pops to mind is it might be coil whine. WHile I haven’t had this on my GemiBook so far, I know I did have it on some of my prior Chuwi laptops.
