I use stm32h7r3 to develop USB audio recording function. My device can work successful in Ubuntu/Android/Windows, but failed in iOS. I had tried many iOS version, but still can't work. The below is my device USB parameters:
2 channels L/R
32 bit data length
48KHz sample rate
High speed
UAC1.0
my reference code(stm32F769I) from https://www.st.com/en/embedded-software/x-cube-audio.html
Could someone give me some advice?
