[Bug 1876065] [NEW] After unplug headphones and plug them again no sound can be heard

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Ubuntu Foundations Team Bug Bot (crichton):

After startup with headset plugged in they play sound nicely - no issue.
When they are unplugged, the sound is switched to the speaker (laptop) -
all good. However, when I plug the headset back there is no sound. I see
the app on pavucontrol, the volume is fine - everything looks fine
except there is no sound. I dumped output of "pactl list" command on
startup (headset plugged), after unplugging the headset, and when it is
plugged back. From the comparison of these outputs, it looks like the
source has got muted after the headset is plugged.

Source #1
	State: RUNNING
	Name: alsa_input.pci-0000_00_1f.3.analog-stereo
	Description: Built-in Audio Analog Stereo
	Driver: module-alsa-card.c
	Sample Specification: s16le 2ch 44100Hz
	Channel Map: front-left,front-right
	Owner Module: 7
	Mute: yes

Attached three outputs:
headset-in.txt - after startup with headset plugged - all fine.
headset-out.txt - after unplugged headset - sound through the speaker - all fine.
headset-back.txt - after plugged headset back - no sound.

Any help greatly appreciated.

Regards,
Roman
