Recent Update cancelled aux/headphone cable connection
My vehicle's aux input is the only way to play my iphone audio for applications that I use for music and navigation. I have the Apple-made adapter that plugs lightening end into the iPhone and has a aux/headphone jack input on the other end. I have been successfully using this with all of my iPhones, including this iPhone 11.
Suddenly, when I try to use it, it is not switching the audio and instead continues to play through the iPhone's internal speakers. The car stereo shows the cable is connected, and goes silent in anticipation of incoming audio.
I tried searching in the iPhone settings for "input," "audio," but I have had no luck finding where I can locate the audio output options. Resetting my phone is not an option, as I do not have time to look up usernames and make new passwords for dozens of websites and apps.
iPhone 11, iOS 16
