Hello, I plugged an i2s microphone like this on an ESP32: SD → io 22 WS → io 5 SCK → io 21 I activated Audio reactive and configured wled as below but nothing happens, no LED reaction. ![IMG_5377](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/1/1f17b2c1b6f69340fc0512128a54e3c65f1d1ed6.png) Thanks again for your help. ---

Better if use standard pins for audio usermod. ---

Hello, Thank you for your reply. If I reset my eps32 and do as in the video below, should it work?

its a chris maher video, so probably no. most stuff he does is incorrect. ---

do not use dupont wires if you have any problems, they are unreliable: use soldered wires. try this: [https://mm.kno.wled.ge/WLEDSR/Digital-Microphone-Hookup/](https://mm.kno.wled.ge/WLEDSR/Digital-Microphone-Hookup/) ---

Hello, I’ve started from scratch. I reinstalled my ESP32 and soldered the i2s on the default pins after installation (32,15,14). The L/R of the i2s is soldered to ground. The i2s is an INMP441. I activated AudioReactive in WLED and rebooted by pressing the Reset button. There is no reaction with the sound. Here’s my configuration: ![IMG_5381](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/e/ecf9d45b9b68ff511c6b2b1f05040a4edb507518.png) ---

I have a question about my problem. Is my ESP32 (ESP32-WROOM-32S) compatible or powerful enough for AudioReactive? My ESP32 is this one: [https://fr.aliexpress.com/item/1005006456519790.html?spm=a2g0o.order\_list.order\_list\_main.45.34785e5bClX0B6&gatewayAdapt=glo2fra](https://fr.aliexpress.com/item/1005006456519790.html?spm=a2g0o.order_list.order_list_main.45.34785e5bClX0B6&gatewayAdapt=glo2fra) Thanks ---

yes, its powerful enough. Either your config is still wrong (wrong pins set), your wiring is not good or your microphone is broken. ![image](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/4/4a15b1eaba25931a9975acc700a0aa84ee1fd962.jpeg) ---

the wiring is good, I’ve soldered pins D32, D15, D14. I’m going to order another I2S to try it out. Thanks ---

you are missing my point. look at the picture. ---

> [@dedehai](#): > > you are missing my point. look at the picture I think I’ve figured it out, I soldered the i2s on pins D32, D15 and D14 and set up Wled like the capture in the post above. Did I miss something in your picture? Thanks ---

on your board, are the pins exactly like that? numbering and all? use a multimeter to check if all GND are actually GND. there is a lot of bad clones. ---

that looks right. so either broken mic or bad connection, assuming you triple checked GPIO numbers and GND connections. ---

ok thanks for your answers. I’ve ordered another INMP441, I’ll test it tomorrow. ---

Hello, Happy New Year to all. I haven’t changed my I2S yet but in the wled info I see that it is marked quiet is this normal? ![IMG_5383](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/3/34bae64d7c2f38b00e1ee03343cb653ae6449950.jpeg) [Next page](https://wled.discourse.group/t/wled-audio-reactive-with-i2s-microphone/13716.md?page=2)
