Hello everyone! My first post here. Hope you are doing well.

I searched for similar problems on this forum, but my problem is a bit different from others similar to this. 

So i have this cracking sound problem for a while now. It started happening only when unplugging power cable,it would happened sometimes, now is more frequent and it started happening sometimes when playing videos on YouTube. Want to mention that i recently changed thermal paste and thermal pads,so temperates are really good ,79 Celsius CPU Avg, and 60 Gpu avg under stress test so that is not thermal throttling . Btw problem was there even before new thermal paste and pads applying. 
Tried few solutions with changing quality of playback device to cd quality, removing effects and enhancements. Made sure all drivers are up to date, fresh windows . Playback sound device set to default. Checked if there is some latency with DPC latency checker, and with latency monster. Seems like everything is fine there. 

Now i am aware it could be power cable or charger fault ,but not completely sure because when i disable speaker/sounds, there is no cracking sounds, so its not motherboard making sounds or just static in general. ? It seems like problem is in speaker and sound. Does static happens even if speakers are disabled ? 

I recorded it with both sounds ON and OFF and uploaded to my google drive if u want to check.

Hope you can help me, its becoming annoying and i am worrying that charger could be faulty and that could be dangerous of course .

Hope you are having great day. THank you in advance!
