iPad sound-Games mute but everything else is fine.

Hi 🙂

I recently bought a new iPad. I set it up and everything was working perfectly until a couple weeks later when I notices that my games were starting to mute themselves, or something. It started with one game and eventually effected all of them. Movies, videos, Internet and some alert sounds still function. I've been up and down with trying to figure out which button/part of system settings to use to get the sound back on for everything. Any ideas?

Thanks 😐
