[HDA-Intel - HDA Intel PCH, playback] Gnome settings does not display / detect rear/front headset

Gnome-settings does not display the front panel / headset as an output device, only the displayport audio outputs are shown. See the attached screenshot.

ubuntu-bug does however play stereo sound out of the headset during the test procedure. I'm not sure this is a bug in alsa unless it's related to an autodetect or configuration issue.

This is on a intel 10th gen NUC,
