Surface Pro 4, annoying noise from the back!

Guys, I'm having the exact same problem with a SP4 128 gb Intel Core M! I have been using it for a week, but it only started tonight!

What's exactly the solution which would affect the battery?

I tried to rule out the audio/speakers in a few different ways - disabling the audio device in device manager, uninstalling the audio device in device manager, plugging in headphones, etc.  Unfortunately, the sound still is coming through :-(   We'll see what the Microsoft Store tech says tomorrow since I just got done replacing the device...  I really really REALLY hope that I don't end up having to just return it all together - the SP4 rocks, otherwise!

This could be linked to the audio devices (speakers). I mean the sound/noise generated from other hardware modules (graphics, touch...) could be bleeding through the speakers while scrolling web pages with rich contents, watching videos, high brightness settings, white screen contents...

Try muting the audio and check it if you can still here the noise.

I would suggest replacing the device otherwise.

Can someone explain why the back of my surface pro 4 (only when the brightness isn't 0% or 100%) makes a noise?

For example, when it is on 25% of brightness it starts making a strange noise slight like a whistling...

Can someone help me?

Can we confirm what model Surface Pro 4 everyone is having this high-pitched noise with?  I would like to figure out whether the high-pitched noise has anything to do with model.  I have the Core i5 4GB/128GB version

**I tried this registry change, but it did not remove the problem.**

Also, my separate thread regarding a high-pitched noise has been folded into this thread.  Does anyone have any further ideas about what could be causing this high-pitched sound?
