I have purchased used laptop for 7 months, NEC PC VK18VKEFWDG with windows 10, it has excellent sound on built in speakers but when I plug in headphone (TRRS, the only one port) it sounds very bad. Sometime, ticking sound and sometime static noise, where sometime is seems like it chop bass frequencies. Sound quality go down as battery drops but sound good when plug in OR fully charged. I increase volume on VLC over 125 in headphones, sometime help the sound quality. Furthermore, it has good sound on low volume and bad on higher one.
For first 5 / 6 months it was present but not much noticeable. I was using "halfway entered method" to overcome the noise problem.
I have installed various drivers like RealTek, through DriverEasy and DriverBoost but doesn't work. The headphone are excellent on other devices and I tried 2/3 sets of headphones but all has same problem.
I tried Kali Linux through live USB, the noise is present there but comparatively less.
