There seems to be a power saving issue where the sound card automatically turns off when not in use. When the laptop is off the charger, I plug in the headset into the headphone port. Then a sharp popping sound is sent through to my earbuds to my eardrums. You often have to manually disable the power saving to stop the issue, but this impacts the battery life of the laptop. I noticed this issue on Ubuntu MATE first and if has occurred on ALL versions of Ubuntu MATE I have used {16.04 onwards}. This issue also occurs on other Ubuntu distros.
Here is the specific Audio hardware
jgj@jgjbuntu-Inspiron-5547:~$ lspci | grep Audio
00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 0b)
00:1b.0 Audio device: Intel Corporation 8 Series HD Audio Controller (rev 04)
