iPad trying to airplay to microphone

[kokomodo]

I have a TASCAM iM2 connected to an iPad Air 2 (iOS 15.8.4) through the lightning port. I can record fine, but with the microphone connected, the output tries to airplay to the mic. Obviously, this doesn't work as the microphone is a simple stereo microphone with no bluetooth or speakers. I've tried turning off "automatically airplay to tvs" in the iPad settings. I've also tried turning off the wifi on the iPad as well. Multitrack still tries to airplay to the mic. If I unplug the mic, the audio plays through the iPad speakers as it should. Is there a way to disable airplay completely in MultiTrack or to tell it not to airplay to that device?
