Rpi aux jack not detected

Hi I am trying to route audio output through the aux jack and video through hdmi.
In the GUI settings > system > audio > audio output device only displays an option for hdmi out.

aplay -l

I attempted some troubleshooting including the fix from this thread but nothing thusfar has worked.

It is not a hardware issue - I swapped to an sd card with raspbian and the jack works.

Any ideas?

==============================================
Update
issue fixed thanks to @fzinken
To enable the 3.5mm jack append the folowing to /boot/config-user.txt

dtoverlay=pisound
dtparam=audio=on

Try this
