A jukebox summoned by a command block won't play any music. If you put the record in by hand everything works perfectly fine, but if you try to recreate that with a command block the game doesn't play the music. I even tried using /clone to copy a jukebox, but didn't work either.

My command:
/setblock x y x jukebox 0 0 {RecordItem:{id:"minecraft:record_cat",Count:1b}}

I even tried to adjust some values like
/setblock x y x jukebox 1 0 {RecordItem:{id:"minecraft:record_cat",Count:1b}}

But nothing works. Also the only way to put in a record is with the hand, but I want to automate it (for a server)

Also, I'm using a resource pack changing the music file, but the music plays when I put in the record manually.
