IPhone volume not working?

I have a iPhone 7 Plus. When I go to settings and I go to sound and adjust the volume it makes the sound for it and if I turn off my phone and turn it back on it makes the charging noise while it's in charge but if I go into snapchat or receive texts it doesn't make a noise it just vibrates I tried restarting many times what's wrong with it

Nvm guys I had it connected to a Bluetooth lmao
