Just installed Cubase 11 alongside Cubase 10.5, which I’ve been running since it came out. Interestingly, Cubase 11 inherited all the exact routing from 10.5 for my Inputs, Outputs, External Effects, etc…but when engaging the Control Room talkback mic, it doesn’t work (can’t hear the talkback in the headphones).
Using the exact same settings in 10.5, Talkback works exactly like it should. Routing is the same for both versions.
I suspect it’s a bug since my routing is correct and is exactly the same as 10.5 routing.
