Cast media and tts to google mini

HI all
I’m trying to create an announce through Google home mini.
I went through forums and previous conversations on the subject to get started from the ground up.

I currently cannot cast TTS or MEDIA, Google Home or Android TV.
The devices are visible and I see them on the lovelace dash board, and can control the volume.
Once I CAST I hear Chime, and that’s it.
Home Assistant OS 5.12

how can i start to figre out the solution?

The same happened to me back in december.
All TTS stopped working. My solution was to start a Nabu casa account.

I have Nabu casa, and google options are on and working on browser (on test section).
