TTS - Google Devices not playing tts mp3 files

Home Assistant installed with MQTT on Proxmox VM.
All MQTT devices and automation are working successfully.
Google Cast integration installed with 3 Google devices installed that I can command with “Hey Google”

Now I am attempting to have TTS provide notifications via the Google devices.


No issue browse media and play music from radio selection.

However attempting to use the TTS with text typed in, the Google device chimes but no audio is heard.

Obviously I have missed something in the configurations, but I am not familiar enough yet as this is a new project… any help in direction would be greatly appreciated… hope the screenshots are of use in determination…
