You turn sounds off and on from Board and Pieces in Settings. Possible that it got turned off through some kind of glitch. It looks like this (and don't forget to hit the orange Save button when you are done).
No sound while playing

Wow, thank you so much. I tried the board and pieces settings already but never thought of the save changes button. It all works now
I’ve had been playing only 10min without sound for quite a while so I decided to play bullet one day, but the board was completely mute even when I increased the volume of my device which is super annoying when playing bullet as I can’t react to my opponent’s move quick enough. Since I haven’t toggled with any of the settings, I think it’s got to do with the server. Anyways, this has been continuing for some weeks and I can’t seem to find a way to fix it; I need help!
