Does that mean you do not have pulseaudio running? I am still confused whether all my apps would just run fine if I install pipewire and remove pulseaudio, or whether pipewire currently takes over only some of the responsibilities of pulseaudio.
Zero PulseAudio, just the `pipewire-pulse` daemon (that replaces it). Better yet, all PulseAudio clients that I tried just works (including things like `pavucontrol`).
Yes, you need to uninstall the PulseAudio server, it is not used anymore. PipeWire implements its own pulseaudio server that talks to PipeWire.
