Hello,

I have a Fireface 800 connected to a 2009 Mac Pro. I just updated my OS to El Capitan. It works well with my DAW (Nuendo), but I cannot switch the outputs of the Fireface in El Capitan itself to ADAT 13-18 in the Audio MIDI setup. Every time I close the Audio MIDI Setup it changes the outputs back to Output 1-8. Also, I cannot use the Fireface with Facetime. People can hear me, but I cannot hear them. So El Capitan does not seem to communicate correctly with the Fireface. Has anyone experienced problems like this?

Best wishes,

Nico
