Lost media playback and tts.cloud_say through google devices

Home Assistant OS, Core 2026.4.2

Some time ago I lost all playback through the google devices, and I can’t figure out what is wrong.
I’ve removed the google cast config, and readded it, to let all the devices reappear without any old config messing it up.
But it says nothing.

Simple action like (request is made through developer tools).

action: tts.cloud_say
data:
  message: Hej, jeg hedder Google
  entity_id: media_player.googlehome6416

And the entity_id is copied from the device list.
Nothing, it turns on the device with the ‘blurp’ it gives, but no audio.
The volume is set at 50%, and I can hear that I can adjust it up and down through HA.

I also tried playing some media stored on Home Assistant (also built in developer tools)

action: media_player.play_media
target:
  entity_id:
    - media_player.googlehome3265
data:
  media:
    media_content_id: media-source://media_source/local/two_tone_doorbell.mp3
    media_content_type: audio/mpeg
    metadata:
      title: two_tone_doorbell.mp3
      thumbnail: null
      media_class: music
      children_media_class: null
      navigateIds:
        - {}
        - media_content_type: app
          media_content_id: media-source://media_source
      browse_entity_id: media_player.googlehome3265

Again, it wakes up, but no audio?
This has worked for years, and only just recently stopped.
I sometimes hear the Google Devices keeps trying to play back the audio, and keeps giving the ‘wake up chime’ and the only way to make it stop as far as I can see is to power it off.

Mine is down or intermittent the past few days as well.
