Hi Jo and thanks for your bug report.
According to your BIOS, node 0x1b is your headphone output but the
driver thinks it is at 0x19. Could you please try the following:
Edit the file /etc/modprobe.d/alsa-base.conf and add this line:
options snd-hda-intel model=auto
Save and reboot. Let me know if this solves the problem for you.
Thanks!
