How to Redirect Sound Output to uPNP/DLNA-Receivers?

I would like to redirect the sound of my system to some uPNP/DLNA-speakers around my house.

Obviously this was possible with Pulseaudio-DLNA or Pavucontrol in the past, but I cannot figure out how to do so with a current system.

Any knowledge about this? :grinning_face: Thank you very much!
