Theres no reason to upgrade before they actually comply with eus right to repair act, and the older one that says they gotta allow other app stores etc (i do believe that will have to be enforced by the end of next year)
I tried to solve my audio issue yesterday (im a new linux user)
The audi from hdmi -> monitor is scratchy.... most of the time
Guide says uninstall pulse audio. I run the terminal command, cant do that because of popOS desktop requires pulseaudio. Ok. Cant remove popOS desktop either because it will break stuff.
Cant install new audio software either because it conflicts with what i got already..
Found an issue posted on github about it from 2019.. "issue closed"
Godot is FOSS.
Unreal is decent too i guess but.. not free. (Though iirc its free if you publish your game on epic)
