IPad video w ICA4+ doesn't work ...

I've got the ICA4+ fw 1.0.8 and an IPad Air IOS9.2.
48KHz, Clock Source set to USB port connected to IPad.

Recording using Garageband or Auria works like a charm !

But recording a video using the built in camera app doesn't ...
Pressing the record button starts the recording (I can hear the 'pling'), and the stops immediately without recording anything ...

Known issue ?
