So it's been a long time since I got this bug very annoying and this is bothering me too much. This happens at some random moment and when this happens, all the sounds in my game disappear as if I was left the whole game in mute, even though I go back to the game menu, the sound only comes back when I close the game and open again
Device: LG K10
Thank you for your report!
However, this issue has been closed as a Duplicate of MCPE-30843.
I think this is likely to be the same issue, and it's because the device is low on memory, so only a few sounds will load in.
