Audio plugin for JBL SoundBar 5.1

Would it be possible to get an audio receiver plugin for the JBL Bar 5.1?
It shows up as a chromecast device, has an IP on the network
Link to the mfg product website Boutique Officielle JBL – Enceintes, Casques, et plus !
I have tried the UPnP and LG plugins and neither have worked.

Please let me know what other info you may need.

Thanks much,
Barak

Sorry but I can’t write a plugin for a device I do not own as no way to test.

On Yatse side all is public GitHub - Tolriq/yatse-avreceiverplugin-api: API and Sample for Yatse Audio/Video receiver plugins and you can try to build one yourself.
