I have a Galaxy Book (2017) that I recently installed Kubuntu on and discovered that the speakers don't work, after some research it seems I'm not the only one who had this issue. Others have been able to fix the speakers using sof-firmware and verb lists, I've tried using lists for ALC298 but it still isn't working, I can't really use this tablet without speakers so any help would be appreciated.
The Fedora and Debian thread solution should definitely work with Pipewire, as both those distros comes with pipewire default and no changes are discussed.
make it executable with chmod +x necessary-verbs.sh
Create a systemd service in /etc/systemd/system that runs the script at startup: [Unit] Description=Run internal speaker fix script at startup After=getty.target [Service] User=root Group=root Type=oneshot ExecStart=/usr/local/sbin/necessary-verbs.sh RemainAfterExit=yes [Install] WantedBy=default.target
