Dragonfly DAC and 96000 hz flac files



I just tried to play a flac file that is encoded in 24bit/96KHz with VOX for IOS on my iphone 6s. I thought VOX supported this sampling rate but my Dragonfly DAC shows a green light which signals that it is being played at 4100Hz.

I don’t understand where the problem is. I know for sure Dragonfly supports this sample rate and in principle the iPhone model I have does as well provided one uses a player that supports it. I thought VOX did. It certainly does on my Mac.

I would appreciate any information or tips anybody here might provide.
