Alarm_stream only vibrating

Hello,

I have a automation to notifiy me about someone being at the door. This automation has always worked great, but now it is not loud anymore its just vibrating. I am on Android 15 Beta QPR2 and my media settings are everything loud except notifications. This can be seen in this picture.

This is the automation:

  alias: Klingel
  description: Klingel aktiviert eine notification am handy
  trigger:
  - platform: state
    entity_id:
    - binary_sensor.klingel_channel_1_input
    from: 'off'
    to: 'on'
  condition: []
  action:
  - service: notify.mobile_app_pixel_6
    data:
      message: Es ist jemand an der Tür
      title: Ding Dong!
      data:
        ttl: 0
        priority: high
        channel: alarm_stream
        actions:
        - action: DOOR_OPEN
          title: Tür öffnen
  mode: single

Does anyone know why the alarm_stream is just silent now? Is this a bug with android or home assistant?

Greetings

try checking the channel properties maybe the sound changed somehow? that is not app controlled, the app can only create it once and set the sound as the default alarm stream and after that we have no control of it.
