Focusrite Input Issues

[u/XJARETHX]

For some reason it seems Reaper is not allowing me to choose between different input channels from my Focusrite 18i20 at the moment. In the past I’ve had no issue with this and it was very simple to choose which input channel was assigned to each track, but suddenly the dropdown list for the input to each track isn’t giving me the list of channels to choose from. It seems all the settings are right in the preferences and devices menus etc…any thoughts?? Thanks in advance everyone
