I've got a very annoying problem for months now: without me turning it off myself, nor my phone being in the "don't disturb" mode, my phone switches off all sounds itself. Not sure when it occurs, but I suspect whenever it goes to a Screensaver mode. I've checked every menu option regarding sounds, but can't find anything that prevents this from happening.
