Title:
  Pipewire uses 100% of a CPU core. Can not connect to pulseaudio.

Status in pipewire package in Ubuntu:
  Incomplete

Bug description:
  pactl commands freeze and don't display anything. pavucontrol tells
  "Establishing connection to PulseAudio. Please wait...". Audio does
  not work in system. This issue is reproduceable sometimes. I don't
  have information on how to give first-aid in this case. I'll just kill
  the process and try to restart pulseaudio.
