# This script will attempt to enable pipewire as the default audio server.

# Disable this, as it is almost certainly left over from when pipewire
# used to store its config file in this location:
if [ -f /etc/pipewire/pipewire.conf ]; then
  for file in /etc/pipewire/*.conf ; do
    mv ${file} ${file}.obsolete
  done
fi

# Rename the XDG autostart files:
for file in /etc/xdg/autostart/wireplumber.desktop.sample /etc/xdg/autostart/pipewire-pulse.desktop.sample /etc/xdg/autostart/pipewire.desktop.sample ; do
  if [ -r $file ]; then
    mv $file /etc/xdg/autostart/$(basename $file .sample)
  fi
done

# Disable pulseaudio.desktop:
if ! grep -q "^Hidden=true$" /etc/xdg/autostart/pulseaudio.desktop ; then
  echo "Hidden=true" >> /etc/xdg/autostart/pulseaudio.desktop
fi

# Edit /etc/pulse/client.conf to disable autospawn:
sed -i "s/autospawn = yes/autospawn = no/g" /etc/pulse/client.conf
sed -i "s/allow-autospawn-for-root = yes/allow-autospawn-for-root = no/g" /etc/pulse/client.conf

echo "PipeWire enabled as system multimedia server."
