Thanks for the response. I tried that but to no avail. On the bright side, I may have solve the issue anyway.
The cause may have been one of two things:

1) I disabled the "Exclusive Mode" options in the Windows sound settings for both playback and recording, apply, OK, and restarted. I tried this before with no luck, but without restarting. Maybe restarting was necessary, even with the "apply"?

2) The brand new, my-tee-fine USB-C cable from IKEA didn't seem to agree with the system once I started trying to record. Once I swapped it out with the one that came with the interface (yeah, I know), it worked.

Thanks for being available and willing to help a n00b!
