media_player.play_media no longer working with Fully Kiosk devices afte r 2024.11

[stuartm]

The problem

I have a couple of automations that play sounds (mp3) on Tablets using the fully kiosk integration. These were working great right up to 2024.10 but after the upgrade to 2024.11 I only get the following error popup on the Tablets (appearing after several seconds).

"Failed loading sound: Wrong URL or unsupported format?"

Installed versions of Fully Kiosk are a mix of 1.54.1 and 1.56.2. The tablets themselves have no internet access and therefore haven't been updated or changed in any way for a long time. The only change was the update to 2024.11 from 2024.10, the issue being noticed almost immediately after the upgrade of Home Assistant.

What version of Home Assistant Core has the issue?

2024.11

What was the last working version of Home Assistant Core?

2024.10

What type of installation are you running?

Home Assistant Container

I noticed your issue and tried if I could replicate it on my setup. But it works fine. My settings are more extensive though:

target:
  entity_id: media_player.tablet_57
data:
  media_content_id: >-
    media-source://media_source/local/Door-Bell-Ding-A2-www.fesliyanstudios.com.mp3
  media_content_type: audio/mpeg
metadata:
  title: Door-Bell-Ding-A2-www.fesliyanstudios.com.mp3
  thumbnail: null
  media_class: music
  children_media_class: null
  navigateIds:
    - media_content_type: app
      media_content_id: media-source://media_source
continue_on_error: true
action: media_player.play_media

But it also works when I cut it down similar to your code:

target:
  entity_id: media_player.tablet_57
data:
  media_content_id: >-
    media-source://media_source/local/Door-Bell-Ding-A2-www.fesliyanstudios.com.mp3
  media_content_type: audio/mpeg
action: media_player.play_media

I'm running FK version 1.56.2-play on a Samsung tablet
