Is my interface (iD14) cooked?

[VoiceofDuum]

Hello! Just getting to know REW and would love to use it to equalize some rooms, starting with my home studio. Windows 11 laptop, Audient iD14 MkI interface, Sonarworks SoundID Reference mic. Current snag is early, at the soundcard measurement step. I can't get the input level closer than 8dB from the output. If I adjust anything else I can find upward (hardware input knob, hardware output knob, software iD14 mixer level), then input starts feeding back on a different frequency. If I run the measurement anyway (with levels as shown), REW warns me it varies by 28 dB between 20Hz-20kHz and is likely crap (to paraphrase).

Known-good 1' TRS-TRS cable for the loop. iD14 has latest firmware (1.1.1). Power adapter connected although phantom turned off.

Am I screwing it up or is my iD14 not up to the task?

You have monitoring active so the input is being mixed back to the output, you need to disable that.

Thank you! It could very well be I am not smart enough to use your amazing software. Just in case, though, I'm following up.

I don't know where to disable monitoring in this context. Do I do that in Windows, Audient, or REW?

Pic attached shows where I am. Maybe you can spot something additionally dumb I'm doing. When I crank the output on the iD14 all the way, REW's input meter gets up to about -20.

Set up the Audient so the output is "DAW Thru".
