I'm running Ubuntu 20.04 on a NUC107i. The system does not appear to recognize the 3.5 mm headphone jack with mic. When I plug in a HDMI monitor with speakers, the audio comes through the monitor fine, but I'm not able to get any sound from the headphones. The Sound Setting do not give the 3.5mm jack as an option. When I plug in a monitor with no speaker, I get the "Dummy Output" as the only option. How do i get the system to recognize the 3.5 mm jack?

I had the same issue with Ubuntu 20.04 while it worked for Ubuntu 18.04. From similar problems with older versions I got this, which helped:
sudo apt install pavucontrol
pavucontrol
This magically switched the sounds to my headphones and showed them along with the microphone also in the standard sound settings dialog. It is also permanent: If I unplug my headphones, sound switches to HDMI and if I plug them in again, sound switches to headphones again. Now my headset is finally working under Ubuntu 20.04 on my NUC 6i.
Thanks Nico...problem solved exactly as you indicated.
Also migrated from 18.04 LTS to 19.0 to 20.04 LTS and had the same problem just recently. Initially no problem with 20.04 LTS. My laptop:Lenovo-ideapad 320.
Enjoying my earphones again !!
I found a better way from the Intel community forum.
alsa-base.conf
file withsudo
:4.Reboot
Now, when you plug in your headphones, a “Select Audio Device” dialog will appear:
