[arch-general] pavucontrol depency question

Hi all, some time ago xfce sorted out xfce4-mixer in favour of xfce4-pulseaudio-plugin. - agreed removing xfce4-mixer - Installed xfce4-pulseaudio-plugin - no sound mixing available at all - Installed optional dependency pavucontrol - no sound mixing available - no connection to pulseaudio server - Installed optional dependency pulsaudio - yay! sound mixing up an running. I don't understand much about dependency quirks but I wonder about the reason both dependencies beeing made optional. xfce4-pulsaudio-plugin is out of any functionality without working pavucontrol pavucontrol is out of any functionality without a running pulseaudio server. So what is the reason making both dependencies optional? -- Friedrich
