Dell Vostro 5568 - Sound device disappears after connecting headphones

[TJ]

With all kernel versions so far tested including mainline v4.15.4 the audio device permanently disappears even after a cold reboot once the headphones have been plugged/unplugged.

Looks to be a firmware issue; latest firmware has been installed but issue remains.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

@Sorfrost: The acpi tables attached are for some reason not complete and cannot be disassembled.

Please do "sudo apt install acpica-tools" and then

sudo acpidump | gzip > /tmp/acpidump.gz

and attach /tmp/acpidump.gz to this bug report.

Only seems to occur when the PC has been connected to AC charger for a very long time. Unfortunately I cannot reproduce that situation at the moment.
