Hello Mojang,
I was testing snapshots and I wanted to hear the song "cat". I put it in the jukebox, waited, and nothing happened. I put other discs in there and still, nothing. Please fix this bug, because I really want to hear my favorite Minecraft song, but still want to sit around my campfire and not go back to 1.13.2.
Please make sure that the volume slider in "Jukebox/Note Blocks" is not set to OFF.
I cannot reproduce this issue. Please close Minecraft and the Minecraft Launcher, and then start Minecraft again. Does that solve it?
