Microsoft Surface Pro 4 Crackling Sound

Microsoft - please see my post from September 1, 2018 for the offending event from the Event Viewer.

PLEASE NOTE: This same event happens EVERY SINGLE TIME concurrent with the crackling sound.  It has been reproduced daily for the LAST SIX MONTHS.  When an issue can be reproduced HUNDREDS OF TIMES and the same event shows up every time, it is clearly related.

It's absolutely befuddling to me that the user base has provided Microsoft so much information and your development team can't figure this out.  My guess is that there is absolutely NO communication whatsoever between the Windows 10 OS development team, the Surface hardware team, and the folks who moderate your web site.

PLEASE FIX THIS.

A workaround while M$ goes ahead and ignores this problem...

shut down the Surface instead of sleeping... it boots super fast so it’s not a huge inconvience, and shuts down the speaker so no more noise.

I also have this crackling issue.  At first I thought that my neighbors in the next apartment were tapping the wall but I realized the sound was coming from inside my bedroom, which is where my computer is.   Just quite loud crackling coming from the hardware.  I have not found a pattern for mine yet.  But it definitely does it when the computer is off and should be sleeping.

I have this issue intermittently on my Surface Book connected via SurfaceDock DisplayPort to an LG Ultrawide Screen which then has the speakers plugged in to it. I have two machine plugged in to the screen, the SB by DisplayPort and the second machine, an HP EliteBook, via HDMI. The HP does not suffer the problem. 

The crackling will start at random, no movement of the device, cables, etc. Once it starts disconnecting and reconnecting seems to address the issue, whether that means disconnecting the dock from the Surface Book, or powering off the monitor and back on. It may not happen again for days or it could restart within a few minutes. 

No obvious failures record in any of the event logs around the time of the issue. 

Running 1809 (17763.134), but has happened across production and pre-release builds.

I also have the crackling noise on my MS Pro 4 when in sleep mode.. Just 2 weeks ago I had my previous Surface Pro 4 replaced by a new one because of the common screen flicker problem and now this happens. My previous Surface Pro 4 also made the crackling noise when in sleep mode but I thought it was because there was something wrong with my headphones. Well, this is clearly not the case since my brand new Surface Pro 4 has the same issue.. On my old device I figured out that the sound does not appear when I turn my volume off before activating sleep mode. This also seems to help with my new device. But still, it is super annoying and also makes my class mates jump sometimes when I forget to turn of my sound.
