The Qobuz iPhone app does not play through a DAC connected to iPhone w/Apple camera adapter
The Qobuz iPhone app does not play music through a DAC connected to my iPhone using Apple's “lightning to USB 3 camera adapter.” All connections seem tight. The iPhone qobuz app shows music playing but there is no sound. What could be wrong?
Detail 1) If I unplug USB cable from phone's camera adapter and plug it into my Mac computer, the Qobuz computer app plays perfectly, so the problem must be in the phone or phone app, right?
Detail 2) When I first connected the camera adapter, a window popped up asking if I wanted to update the camera adapter. I clicked ok and it took a minute or two to update. Was that a mistake?
