Playing TTS and mp3 in Lenovo Smart Clock doesn't work

Hi,

I’m trying to send some TTS message and playing some mp3 files in my Lenovo Smart Clock integreted via Google Cast integration with a script. When I run the script the Lenovo device receives some information because the screen changes, but it doesn’t play neither the messages nor the mp3 file.

Changing the entity_id in the media_player.play_media service the script works properly with other device, so the problem seems to be in the Lenovo device.

Can anybody help me?

Thanks

Similar problem here. It worked for a couple of weeks then it stopped. When the automation runs it beeps and changes to the media player screen but no TTS. Using amazon Polly.
