After bluetooth use in car Lumia 950 ringer stays off

[Windows Central Question]

So this is a recent development and I may have accidentally changed some setting. I don't really know. The phone works great with the car bluetooth but now EVERY time I get out of the car the phone's ringer stays at zero. I get into the car with the ringer on and get out with the ringer off. It is on vibrate but I have to up the ringer volume every time. What setting did I mess up and how do I fix it? Thanks.
