--- Comment #14 from Sven <brettschneider.s...@gmail.com> --- Just as an update: Downgrading pipewire didn't seem to help me, neither starting the proposed script before login. Tried deleting config files as well as killing pulse-audio, clicking buttons in pavucontrol, removing the kde config folder... Nothing helped so I switched my father's computer to a fresh Kubuntu install. Now he has working audio again. Hope the "no sound" situation gets resolved soon for everyone who's still having this issue!
