In-app sound controlled by ring/silent switch

I'm not sure if this is a feature or not, but if it isn't would it be something that could be implemented in the future? Turning off all sounds such as in-app media player when the side switch on the iPhone is switched to silent? There's been numerous times where I click a video in a public setting (doctors/work/college) to have the sound play when I didn't want it to.

Perhaps turning the switch to ring mode allows the sound to play normally? Or even a toggle option to turn on this feature on and off if only some people want to use it.

Thanks for reading and if it's already a feature I apologize!

--Just a suggestion I wanted to throw out there!
