Critical Notification - TTS not working on S10e

When I try to use TTS for a notification, it just shows up the notification, but without sound.

Yes, of course: My volume is manually set up to 100%, still nothing.

I use this:

automations:
  - alias: "Fire Detected TTS alarm"

    trigger:
      - platform: state
        entity_id: sensor.smoke_alarm
        to: "smoke"
    action:
      - service: notify.mobile_app_<your_device_id_here>
        data:
          message: TTS
          data:
            ttl: 0
            priority: high
            media_stream: alarm_stream
            tts_text: "The house is on fire and the cat's stuck in the dryer!"

I found it here:

Thanks in advance, y’all!

Try this:

- service: notify.mobile_app_<your_device>
    data:
      message: TTS
      data:
        ttl: 0
        priority: high
        volume_level: 1
        media_stream: alarm_stream_max
        tts_text: "We're screwed!"
