Public bug reported:
If I unplug the green plug to my speakers after my computer finishes
booting and then immediately plug it back in again, sound works
correctly.
Prior to the unplug / replug trick the Line-out is missing from Sound settings.
After the unplug / replug trick the Line-out is correctly listed in Sound
settings.
I will attach screenshots.
