Public bug reported:
lsb_release -rd
Description: Ubuntu 18.04.1 LTS
Release: 18.04
I am not sure how to describe the problem.
If i turn off my laptop with my headphones in, when it boots up (without
removing the headphones at any times), then no sound is playing on any exits.
Not on the laptop's speaker, neither on the headphones.
I am a developer, and I think the issue it's that the hardware is trying to
play the sound on the headphones (because you restrict playing on both the
speakers and the headphones at once, without extra custom configurations),
because playing on headphones is what the hardware remembers, but ubuntu
forgets that between reboots and it's telling the hardware to play on speakers,
which the hardware won't do.
To fix the problem, i have to unplug my headphones and plug them back
in. And sometimes that is annoying because some sounds may be too loud
and i am in a meeting :) .
Maybe in ubuntu, the audio port is being initialized with speakers at
boot time, and it is not verifying the aux outputs for listeners, to
initialize with that.
Maybe this should be a new feature.
The feature would be to scan the audio ports at boot time, to see if any
auxiliary ports are found. Not sure if multiple can be found. Initialize
with whatever state would be if those auxiliary ports where plugged in
one at a time, and not found like this. The initial state should not
always be the default audio port.
Thank you for understanding, and please let me know if you what i mean.
