I2S-SDI Problem

VIM3
1

I use i2s SPH0645 Adafruit Microphone with Khadas VIM3 V14. I use Android version “vim3-android-9-32bit-v230720.img”. The problem is that i can’t capture any sound. Can anyone help me?
The connection is:
LRCL (SPH0645) -----> I2S-LRCK(32)
DOUT(SPH0645) -----> I2S-SDI(33)
BCLK(SPH0645) -----> I2S-SCLK(29)

I tested I2S Speaker Adafruit 3006 and works fine.

I tested SPH0645 Adafruit Microphone with Khadas VIM3 V14. I used ubuntu OS and the module works fine.

So the problem in I2S-SDI with Android OS.
