I have just bought the Revelator. When I try to use the loopback settings nothing works until I unplug my interface (Focusrite Scarlett 2i2) which means I then lose my speakers. Even if I set up the sound output in system settings as Revelator Loopback 1 etc. the Focusrite overrides everything. Is it possible to use both together? If I unplug the interface then loopback works fine.
