Hi Simbun,I've had Sonos Play:1s work and the local renderer in BubbleUPnP, but no luck (no audio) with RoPieee or Chromecast proxied renderers.
Make sure you use the app to send feedback after a failed attempt. What RPI renderers are you using?
to answer your RPi question, I am using LMS with the "UPnP/DLNA Media Interface (v1.0) plugin".
My LMS RPi Picoreplayer instance shows up in HiFi Cast as a player on my Android devices.
