Latitude E5450 cracking/poping sound
Hi2all!
I've just bought brand new E5450 5450-7799 (i5 5300U/8Gb/500Gb/830M 2Gb/14"/FHD/Lin/black).
It has originally preinstalled Ubuntu, but right after buying I've install my Win8 and upgrade it to Win10.
I've poping sound coming from speakers (also heared in headphones) while playing music or video.
It's very similar to the issue in this topic. But I've installed all lastest drivers!
This problem linked somehow to hard drive (or CPU?) activity (no matter type of drive - hdd or ssd or even flash over usb).
I've found this problem when I try to watch any Youtube video while coping a lot of data between disks.
Another way to reproduce in Windows for example:
Start (menu) > Control Panel > Sound > Sounds (tab)
Select "Asterisk" (or any other)
Click ">Test" button about once every 4 seconds (if you are too fast the pop will not happen)
You should hear the pop at the start of the sound about 1 out of 4 tries.
Is there any solutions?
TIA
add: I've try to boot from USB with Ubuntu. And there where no poping and all, I run Chrome, start fullHd movie and start to copy 10Gb and Youtube video plays without any clicking and poping. So I guess problem is windows 10 drivers.

Our Windows installation expert says that to get the best performance from Win10, it needs to be clean installed after the upgrade. His instructions

Hello. If you want a reaction from Dell you need to contact it. Tech Support. However the standard warranty does not cover software issues so if you are still within the return period you might consider that option.
The LatencyMon utility has more tools for tracing down the origin of excessive dpc latency than the DPC Latecy Checker..

Thanks for advices.
My installation of Windows 10 is clean now (I've made clean reinstallation after update from windows 8).
And of course I've contact to Dell Tech Support (by phone, by mail, bu chat)...
No luck till this moment(
Dell Support interact like some kind of robot. Try to install, try to uninstall, try to reboot...
I've used LatencyMon. I've got same result with xperf util from Windows.
I'm totally shure that there are drivers problem, and I hope for Dell assistance with this...
