Music Assistant can't play from Jellyfin (but can from Spotify)

[philhzss]

Hi,

I've been using MA with Spotify for a while, and now transitioning to Jellyfin. I am able to connect the library, I see my playlists and tracks, but when I try to play any of them, the play/pause button changes to pause for 1 second then goes back to play (nothing plays).

I'm not really sure what's going on. I can play music off my Jellyfin library with other devices, and since I can see the tracks and playlists it seems to all be properly connected? Found this in the logs, if anyone has any ideas let me know! Thanks.

Does the user you are using for it have download permission?

If you go to a song in MA on its details page there should be a "provider details" link. Under there you should find a Jellyfin link to the track. You should be able to download it / play it from that url. Does that url work?

[philhzss]

I just tried, yes that URL works, I can play the file directly from the browser and also download it using the URL. Hmmm
