I have an issue with my sound system.
Whenever I start my freshly installed Ubuntu 20.04 machine, the sound works just fine. When I plug the headphones, the sound switches to the headphones with no delay, everything perfect so far.
The problem starts when I unplug the headphones: I can hear nothing!
Plugging the headphones again works, the sound will once again be in the headphones, but no sound on the speakers whatsoever.
I checked the sound output device in the 'Sound' menu, the speakers get auto-selected when I unplug the headphones and I can even see the sound intensity on that bar made of green dots. (don't know how it's called).
My machine is a HP Zbook G5 Studio.
Let me know if any of you has any possible solutions.
