When there is noise, please do a test: sudo hda-verb /dev/snd/hwC0D0 0x1b SET_PIN_WIDGET_CONTROL 0x0 #if the noise disappear? sudo hda-verb /dev/snd/hwC0D0 0x1b SET_PIN_WIDGET_CONTROL 0x20 #restore the original value

Something similar occurs with my other earbuds with mic, just much quieter and less noticable. It works fine on Windows 10 running on the same machine, and on my Android phone. I don't notice is when something is playing, but the frequency of the sound changes when I play something, then pause it, the background noise will sound slightly different. This is from an installed Ubuntu 18.10. I have tried booting 18.10 Live USB and 18.04.1 LTS Live USB, and the issue still occurs. I have tried playing with alsamixer and pavucontrol settings, and nothing fixed this background noise.
