I had the same issue with my surface pro4.Since trading it in for a surface pro at BestBuy I no longer have this problem.This must be a issue with an older generation surface.

I've had my MS Pro 4 for a few days now. Updates are installed and it's working fine. I hear a crackling or arcing sound every once in a while. It even happens when in sleep mode. Should I be concerned or is there an explanation for this?

2018-09-01T15:22:20+00:00 The crackling noise occurred again this morning. As my previous post, I immediately checked the Event Viewer. It was perfectly timed with the following event:
INFORMATION: 9/1/2018 11:09:06 AM
Event ID: 1
Source: SpeechRuntime
Audio Orchestrator Power Event: Battery Saver Is Not Enabled, Voice Activation Ready
No other event occurred at that time. So clearly, the crackling is related to this Windows function.
Something I forgot to mention in my previous post. I have a Microsoft Surface laptop and both my kids (in college) have Microsoft Surface Pro 4 laptops. The crackling sound occurs in all three of our devices, so it is virtually impossible that it's "bad hardware." This has something to do with the Windows SpeechRuntime service interacting with the Surface firmware.
Microsoft -- Can you please post whether this is being actively addressed by the development team?

So many firmware updates but they do not fix the problem that needs fixing... Amazing.
