Weird buzzy static on headphones only

I've been having this issue for about a month now. Every time I plug in headphones or speakers into the audio jack I get this weird static noise. I can still hear the music and audio, but when I pause it there's this noticeable buzzy or static sound.

I've Googled it a bunch of times and tried a few different methods to solve it. There's are the ones I tried last time:

• Some people suggest using AlsaMixer to fix it, but I don't seem to have all of the options the solution recommends.
• Entering pulseaudio --check, pulseaudio --k, pulseaudio --D turns off the sound, but when I unplug & replug it's back to the same issue.
• Entering killall speech-dispatcher, which does nothing.

Any idea what else I could try?

System details:

• Dell Laptop: XPS 13 9350
• Operating System: Ubuntu 19.04 disco (x86-64)
• Cinnamon Version: 4.0.9
• Linux Kernel: 5.0.0-32-generic
• Processor: Intel Core i5-6200U CPU @ 2.30GHz x 2
• Memory: 7.7 GiB
• Hard Drives: 125.1 GB
• Graphics Card: Intel Corporation Skylake GT2 (HD Graphics 520)
• Service Tag: 1QCB562
• Express Service Code: 3769578218

EDIT: I'm starting to think it might be a physical or hardware problem. I tried a USB pair of headphones & there was no static at all.

It's weird that my audio-jack headphones have a problem, but plugging audio-jack speakers in is fine. Also messing around with AlsaMixer sometimes fixes it, but maybe that's just coincidence.

I know you have mentioned Alsamixer solutions. But just in case. Have you tried to mute the Headphones mic (if any, all) and/or disable loopback on ALSAmixer? There are many threads on XPS 13 and 15 on this matter (and here is a Reddit on it too)
