This is still happening in Linux 5.3-rc1. Additionally, the
problem also shows up, when starting the (powered-off)
system with the headphones plugged in. No sound is played.
After unplugging the headphones, the internal speaker
outputs the sound. Plugging the headphones back in, sound
comes over the headphones.
Here is the difference in of the states.
