I had been using a Pico dac/amp with my iPhone 5C and the genuine Apple lightning camera connection kit, working just fine until 7.1.1 version of IOS came out. Since then, I now get a "device may not be supported" message when I hook it up, and no sound. GRRR! I thought maybe it would work with 7.1.2, but no joy.
Anyone else seeing this? It continues to work with the iPad both under 7.1.1 and 7.1.2
I am thinking this is deliberate and related to the Beats acquisition. I wish they would make up their freakin' minds, they just ENABLED it when 7.0 came out!
