How to input external i2s into input

Hi,

Currently I'm trying to create dsp and streaming i2s data over wifi. With Bluetooth A2DP, i2s data which received, I sent to other peer over wifi and play it as pcm format perfectly. But when I tried with module Bluetooth I2s module as a I2s input instead of I2s Mem microphone, I play it as pcm but very noisy. this is module https://www.tinyosshop.com/audiob-i2s-bluetooth-digital-audio-receiver-module

So do you know how to play i2s input from external ? Not Bluetooth A2DP internal Thanks you very much.
