this was working like a charm prior 2022.4. When I manually play the scene it gives an error “media_player.bad does not support this service”. What did I miss?
I have noticed something similar. I’m using MPD as one of more media players in my house and in some of my automations I had “media_player.volume_set” as the first action for this MPD player - it worked OK until 2022.4, but then I suddenly got the same error as you in all these automations. As it turns out, I can not set anything (except of “play” or “on” command) anymore until media player is turned on.
So I suppose you didn’t miss anything, just something has changed in the HA code.
I took the problematic items from the scene and added an action after the action for the scene. This worked. From what I can say only scenes are problematic.
