The problem

Music Assistant creates a new login for the Jellyfin media provider every single time it's restarted instead of using a persistent session token or API key. This creates multiple instances of the music Assistant login in Jellyfin (which then also duplicates those as devices in home assistant). I've been using music Assistant for about two months and it created 30+ devices in Jellyfin and homeassistant.

How to reproduce

Docker install of music Assistant server. After connecting to Jellyfin view list of active devices in Jellyfin then restart music Assistant server. A duplicate device for music Assistant will show in Jellyfin active devices. Restarting jellyfin integration in homeassistant will make the same duplicate device show in homeassistant.

Yep on my radar for a while now.

I don't use Jellyfin with HA so the duplicate devices there is a new twist.

HA had the same bug for a while and a Jellyfin dev gave some advice: home-assistant/core#70124

As per that advice, we now use a hash of the MA instance id and Jellyfin username, so even if you totally remove the provider and add it again you won't get a duplicate device in Jellyfin.
