"Track could not be record enabled because..."

I am a newbie pro tools 11 user & I cannot record any tracks because I get the following message:

"Track could not be record enabled because it doesn't have an active input and output assigned."



I've set my playback engine to my HW: Quad-Capture

I've tried to default my input & output settings, to no avail.

I don't see how to map the inputs & outputs to my Quad Capture (though both the input & output show "Quadcapture" at the top of screen box).

I guess I don't understand how the I/O functions & I never had this problem with PT8LE.

I've read multiple existing threads on this topic with no luck.



Thanks for your help as always.
