No sound if booted with the headphones plugged in (have to re-plug them to get sound)

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.

1816271 I get no sound after boot whether or not headphones are plugged in.
If headphones not plugged in, after boot, plugging them in wakes sound.
If headphones ARE plugged in at boot, must unplug and plug in headphones to wake sound.
It's just not waking alsa or pulseaudio. Worked fine until about 14th or 15th.
