Hi all, hoping someone with more knowledge can comment please. 
I have a MacBook Pro running High Sierra 10.13.3 and I can play 44.1kHz multitrack files from Studio One 3 into the USB interface Focusrite Scarlett 2i2 (2nd gen) - no problem.
BUT when using the same setup I cannot hear 96kHz multitrack files 
I've checked all the system settings on the MacBook and also within Studio One 3 but cannot see where I'm going wrong. The cursor silently moves across the timeline screen!
Anyone come across this problem before - any tips gratefully received!
Rod
