Using airplay to play music
I have an iPhone XR running 16.1.1. For years I used airplay on my iPhone to play music from Sirius XM or Amazon Music apps to my Onkyo TX-8160 stereo receiver without entering a password. However, about two years ago, when I tried to play music on my stereo, I would get a message saying "Enter the password for TX-8160". I've never set up a password, so while I can play music using Bluetooth, I'm locked out of using airplay (which I prefer using for lots of reasons). Can anyone help?
