impossible to change audio recording device settings?

hello,

recently i have been trying to use my ipad internal mic to record while wearing headphones

when i connect my headphones, cubasis settings change to use the headset mic to record

problem is, there is no headset mic

in settings there is a display for selected audio device but no way to change

wearing airpods allows me to record but latency makes that not a solution

how can i record from ipad mic while wearing headphones?
