The desktop speakers not working. No sound at all. However the same setup of sound port and speakers work fine on Windows. I am using the Green port for the speakers.

I have the same issue after a recent kernel update. Not sure if the cause is the same, but after about 5 hours looking to the issue, the mostly likely cause seems well explained on this bug comment: https:/
In my case.
Distro v: 20.04.6 LTS
Kernel v: 5.15.0-71-generic
I'm hoping the upstream kernel will have the regression with jack sensing fixed. Via the CLI, I can use alas directly and the sound card works fine, but with pulseaudio, it claims the ports are not available / connected and refuses to default sound output to the analogue line out port because jack sensing fails and even in gnome audio settings it won't list analogue audio as an option.
