In the settings, my sound and music are at 100%. My device isn't muted either. Noteblock sounds still work, but for some reason none of the music discs will make any noise when I put them into the jukebox. The notes still appear above the jukebox and it shows that the disc is playing, but there's no sound. This has been a problem for me ever since I downloaded Minecraft, and has lasted through several updates (Aquatic update, Village & Pillage update, Nether update). I play Minecraft on an Amazon Fire tablet. PLEASE HELP!!
