Pulseaudio sink doesn't appear on list of openHAB sinks


I have openHAB 3 on linux intel, with the pulse audio server and a sink thing already working. I’m able to change the volume and mute the audio on the pulse audio PC.

Both bridge and thing are online, but the sink doesn’t appear on the list of sinks in openHAB

openhab> openhab:audio sinks                                                                                                                                  

  System Speaker (enhancedjavasound)
* Web Audio (webaudio)

Here is the thing

UID: pulseaudio:sink:pablo_AT_Mahler:alsa_output_pci_0000_00_1b_0_analog_stereo
label: Mahler Sink
thingTypeUID: pulseaudio:sink
  name: alsa_output.pci-0000_00_1b.0.analog-stereo
bridgeUID: pulseaudio:bridge:pablo_AT_Mahler


You must activate the option “Create an Audio Sink with simple-protocol-tcp” in the Sink-Thing.
