Subject: Plugged in headphones ignored

Dear Linux folks,

On a Dell OptiPlex 5040 with Linux 5.2-rc6 plugging in a
head phone into the front case connector, it is detected
just fine and Xfce shows a notification.

Then logging out, turning off the monitor connected over
DisplayPort at the end of the day, and turning the monitor
back on the next morning, logging in, the state is
forgotten. I need to unplug the head phone and plug it
back in.

Please find the output alsa-config.sh for the non-working
(1) and replugged (2) situations attached.

Is that a Linux kernel problem, or a user space issue?

Kind regards,

Paul
