Using Teensy 4.0 with Audio Shield as an audio interface Line in and Line out through USB audio to an iPad mini with USB C.
Apps like AUM, Koala Sampler, and Voice Memos have issues with pops in the incoming audio. Issue starts after about 2 minutes of USB being connected. I suspect these issues are related to sample rate and MacOS issues I've seen before on other threads. I am not sure if those fixes that were implemented apply to iPadOS or IOS.

I'd appreciate any help I can get, thank you so much!
