No Sound bug

POV: I open Minecraft, play on a world for a little bit, save and exit without closing the app. I get back on my tablet open recently used apps and choose Minecraft. The bug starts with no sound when I click play on the main menu, or when I click the world, when the world loads there is no sound effects at all. If I close the app completely and restart it, the bug is gone and all sound effects work as they should.
