Title:
[XPS 13 9370, Realtek ALC3271, Headphone Out, Right] Static/Electric
background noise when volume is not muted
Status in alsa-driver package in Ubuntu:
Confirmed
Status in linux package in Ubuntu:
Incomplete
Bug description:
Whenever I plug in my Sennheiser HD1 Wired headphones with mic, I start
hearing a static/electric (some internal?) sound if the volume isn't muted.
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.
