Fixing I2S Initialization Error for Voice-Controlled Home Automation on ESP32

Hey guys am developing a home automation voice-controlled system using MicroPython and TinyML on an ESP32 microcontroller to recognize specific voice commands ("turn on" and "turn off") for controlling an LED, How do I set up the ESP32 with an I2S microphone and an LED for a voice-controlled system? Am encountering an error OSError: I2S Not Found But I have verified the physical connections of the microphone to the ESP32. Re-checked the pin numbers in the I2S configuration. Confirmed the ESP32 firmware supports I2S functionality. Here's my code

from machine import Pin, I2S

# Configure LED on GPIO 2
led = Pin(2, Pin.OUT)

# Configure I2S for microphone input
i2s = I2S(0, 
          sck=Pin(14), 
          ws=Pin(15), 
          sd=Pin(32), 
          mode=I2S.RX, 
          bits=16, 
          format=I2S.MONO, 
          rate=16000, 
          ibuf=2000)

from machine import Pin, I2S

# Configure LED on GPIO 2
led = Pin(2, Pin.OUT)

# Configure I2S for microphone input
i2s = I2S(0, 
          sck=Pin(14), 
          ws=Pin(15), 
          sd=Pin(32), 
          mode=I2S.RX, 
          bits=16, 
          format=I2S.MONO, 
          rate=16000, 
          ibuf=2000)

My aim is to resolve the I2S initialization error to successfully capture audio input from the microphone
