If you don't need 4 inputs, select only what you need.
That shouldn't be your focus here; it adds load to RB.

If you use just 1/2 inputs for recording, select those (only) for inputs.
Or 3/4 .. whatever; don't select extra inputs based on my above image.
I often record 8 tracks at a time, you may not or (probably don't) need to.
It was more of a reference to my RB/Windows settings.

chat/support will be much more likely to solve this weird error message than I, just trying to help


I do not work here, but the benefits are still awesome
