External Mic is very quiet on iPad with USB C
Any iPad with a USB C receives audio extra quiet. We have replicated this behavior with Rode, and Comica mics. We have tried many different adapters, and boosters, and all types of iPads. Each time the audio is coming in 4-5X quieter than the onboard mics. We have tried this with the camera app, garage band, and voice memo. All apps show the audio coming in quiet.
This appears to be a software issue. We have an apple developer account, and when we downgrade the IOS to IOS 14 the issue is no longer present. Anything with IOS 15 and above has this issue.
This thread is the same behavior we are experiencing.
