If you plug in to HDMI and change your output to that HDMI, once you unplug Zorin OS still things your connected to the HDMI sound output however it will remove the little arrow for you to change to the default sound output.
So i usually have to manually search SOUND to get to the sound settings,
however in that little launcher menu where you change sound outputs if the sound/speaker/volume icon was a little quick button to the sound settings (it would save a good bit of time) and also be a QOL feature equivlent to the windows experince of right clicking the volume icon and going "sound and settings"
Epic thank you for the link tried it out and it works for me
definitely something to note since Zorin is using GNOME 43, some newer extensions may not work backwards.
