Title:
Lineout and headphones audio keep switching automatically -- broken
audio
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have been a long-term Ubuntu user (since 10.04) and take pride in
having fixed all problems on my own thanks to the excellent
documentation, but this time I am utterly stumped and have run out of
ideas (hence this report).
With my headphones jacked in, the line out and headphones output
options keep switching automatically, resulting in crackling (and
broken audio). I have tried many solutions I found online but none of
the suggested fixes work. I am attaching a video of what I see (note
that this happens automatically, I don't click anywhere)
This is not a hardware issue (the headphones work fine on another
machine running Ubuntu 16.04, and as far as I'm aware this problem
only appeared after I upgraded from 16.04 to 18.04).
$ lsb_release -rd
Description: Ubuntu 18.04.1 LTS
Release: 18.04
I have uploaded two different videos showing what I see here:
