My friend you have discovered something. I have both the iPad Air (A1475) and iPhone 6S+. I've always been able to use this setup exactly the same in both however I just plugged my Microstreamer in through the camera connection adapter and it isn't working with my iPad. It still works with the phone.
I went through my settings, tried different players-Tidal, iTunes-but none output through the Lightening connection. This is definitely an iOS issue since it continues to work well in my phone. It may be a recent bug in iOS 9.3.1 but its new to me.
Can anyone else shed light on this issue?
