Trouble Playing Plex Music to Sonos from HA

Configuration
1

I am running the latest HA (2021.8.8) with Sonos and Plex integrations configured. Plex is set up in the Sonos system and works. I have a Plex pass, Plex is remotely accessible

However I am trying to send a service call from the Developer Tools to play Plex music on a Sonos speaker but am getting a 403 error in the logs and I can’t understand why.

Service call:

service: media_player.play_media
data:
  entity_id: media_player.living_room
  media_content_type: music
  media_content_id: 'plex://{ "library_name": "Music", "artist_name": "Adele", "album_name": "25", "track_name": "Hello" }'

Error in logs:

Logger: homeassistant.helpers.script.websocket_api_script
Source: components/plex/services.py:136

Anyone else had this problem or can suggest something else to try?

Did this work previously?

Is the Plex integration perhaps configured with a user with limited access?

3

This is my first time using Sonos. I bought a Symfonisk speaker to see if I want to buy in to the whole system.

Plex is set up using the admin user.

4

Have you set up Plex as a music service in the Sonos app?

Please check your HA log file, too.

Yes, Plex is set up in Sonos and works.

Figured it out! More just my lack of following basic instructions!

Went through the documentation again and followed the ‘Sonos speakers linked to your Plex account’ step.

I misunderstood that step for setting up Plex in your Sonos app when it is actually setting up Sonos in your Plex app.

Ah good. It’s a confusing process since you need to set it up in both directions. Glad it was something that makes sense.

Thanks to your log I should be able to catch this scenario and give better feedback on what to do.
