MacOS Sierra : wav or aif sounds recorded with my Zoom H6 won't load in some devices

On my new (albeit 2nd hand) mbp mid 2014 running Sierra, the sounds I record with my Zoom H6 won't load into Samsara. They play normally in Live 9.7.6 and 10.0.2. I checked them on my older mbp running 10.8.5 and it works fine in this OS. To be fair, the situation is exactly the same with Henke's Granulator. Any idea about that ?
