pipewire
does not conflict with any PulseAudio packages
pipewire-pulse
conflicts with pulseaudio
and pulseaudio-bluetooth
pipewire-alsa
conflicts with pulseaudio-alsa
I suggest check pipewire.socket and pipewire.service
systemctl --user -l status pipewire.socket pipewire.service
kpipewire
might be failing to connect to PipeWire If the service is not running
but I don’t use KDE or PipeWire
