I know this issue about the device starting up muted has shown up before here: MUOS sometimes boots without sound but I have the totally opposite problem. I set my settings to startup muted, but recently my device has been starting up at full volume which becomes a jumpscare in public. Sometimes I am unable to lower the volume with both the buttons and the setting screen so I have to restart the device (sometimes a few times) before it starts muted. Please help. Thank you!
