Hi Matthias and/or other RME users,

I work on a macbook running MacOsSierra 10.12.6.
I have a RME Fireface UC and I work on Ableton live 10.
I installed the right drivers and everything should be ok as my computer does detect the USB,
I can even select it as an audio device.

But everytime I do, every audio/video files that I try to play on my computer freezes, video gets paused, ableton gets paused, Itunes etc...
it's not even like it's just muting everything, its more like "I'm pausing and won't answer to any play button anymore".
If I switch to the external speakers it instantly gets back to playing.

I know that the RME does work as I was using it without any problem with my previous computer (a windows 8).
I tried to desinstall/install drivers,
I changed my ableton version and everything but I can't find the solution and I haven't seen anything related to my problem on any forums.
If somebody could help me out It will be greatly appreciated.

Thanks
