New setup - Unifi G4 Pro and Sonos

I am pulling my hair out!

So, i have:
UDM Pro running UniFi OS 4.0.21
Network 8.6.9
Protect 5.1.85

I have a few G4 Pro Cams and G4 Pro Doorbell, i want the doorbell sounding out on my Sonos kit and other speakers on my network.

This was all working fine 12 months ago, using HA on a Docker container on my NAS using an old version of HA, Now i am running it on a home Server using Hyper V -
ThreadRipper 2650 and 128GB DDR5 RAM with an RTX 4090.

I have done a fresh install yesterday of HA and trying to sort it, i just cant get it to work.

it seems the Binary is missing for Doorbell Ring now.

yet i can see the event types.

Please can someone help ?
