When I open Izotope Rx 6 with my Focusrite Scarlett 2i2 set as the audio device, I get the following error: The selected audio device cannot be opened. Please make sure it's not in use by another application and its drivers are up to date. ([0xB]) The bizarre thing is, if I change it to another audio device and then back to the 2i2 it then works fine. Drivers for the 2i2 are the latest version. Any ideas?
