Esc --> Settings --> Music and Sound --> Jukebox/Note Blocks 0% & Blocks 0%. I have now fixed your issue ^-^
Ok then turn your volume back up after???? i really don't see the need to add this just cos y'all are too lazy to take a few seconds to change the volume settings that already exist within the gameI should have included this in the thread. The only problem is that other servers use those sounds to create interactive game modes/experiences. The reason I propose that they add it in game is for ease of access. It is really annoying when I have to go into my settings every time I switch servers.
