Unique Id Error for Chrome Cast Device

[Happy-Cadaver]

I'm running 2024.12.0 beta and trying out the MA native integration, I like it so far and it's inspired me to finally use HA for music. I added, as a test subject, a Google Nest Mini to my player providers which seems to be working fine. However whenever I restart HA I get this in my logs.
2024-12-03 21:12:39.694 ERROR (MainThread) [homeassistant.components.media_player] Platform music_assistant does not generate unique IDs. ID 03a489fa-888c-e412-c376-985042342252 already exists - ignoring media_player.living_room_speaker_2
Yet there's no media_player.living_room_speaker_2 in my devices list, just a media_player.living_room_speaker. Is this a bug I should report? Or am I just not understanding how to set it up, which is likely to be honest. I just hate seeing errors in my logs and this is the only one left to deal with at the moment.

Iirc at the time was suggested to remove this as unique IDs are unique within their own domain, however, because we are creating media_player entities and referencing the original player ID, we are indeed not unique.
@marcelveldt Do we add back the prefix?

[marcelveldt]

No, that is not related.

[jozefKruszynski]

Fair enough, then forget everything I said 🤣

[marcelveldt]

wait... yet it is. HA doesn't use the integration domain prefix but the platform domain. That is indeed going to hinder if you add a cast player from HA to MA (and then back to HA) - Its a bit of a long shot because you shouldn't be using the HA player provider for cast players in the first place.

Do we need to do something to mitigate this?

This will be looked at soon

Thank you.
