I'm currently having an issue with my new IPhone SE when making calls with headphones plugged into a standard 3.5 mil jack, going into the phone via a 2-in-1 lightning adapter. All the other audio coming from my phone goes through my headphones just fine, but when I use Siri to make a Facetime audio call, it switches either to the phone speaker, or the ear piece. I’ve selected each of the 3 options in call audio routing with no luck what so ever.
Is this a known bug? Am I missing something? Could it have something to do with the fact that I’m using an adapter? Any and all help is appreciated.
