Route OP-Z mic input to USB output?

Having some issues using the mic on the OP-Z and getting the resulting audio to output over USB. Works fine if I plug some headphones in, but if I want to record the mic input to say my DAW on the laptop, the mic audio doesn’t seem to work. Normal output of the internal tracks I’m sequencing works fine over USB, but mic output seems to only go to headphones.

Am I missing something obvious here?
