You have to stop pulseaudio.socket and pulseaudio.service
Run sudo systemctl stop pulseaudio.service and sudo systemctl stop pulseaudio.socket
After stopping pulseaudio and testing that your audio is working, make sure the following packages are installed: pipewire-alsa, pipewire-pulse, wireplumber
They should be installed by default if you’ve just installed Endeavour, but there’s no harm in checking.
