Use my mac as a microphone for my iPhone?

Question

I want to use my macbook to play prerecorded sounds so that the iPhone registers it instead of a microphone. Say on a call, or on a different app. I tried connecting with audio jacks but I think my macbook is sending digital audio and the audio jacks are analog. Anyone tried doing this?

Macs from model year 2006-2015 expose both S/PDIF digital audio and regular analog audio on the same single 3.5mm audio port. Newer Macs (model year 2016 and up) only have analog audio.
You’ll want to make sure your audio cable uses TRRS:
