Hello, I’ve just flashed [SR-WLED version 0.13.2](https://github.com/atuline/WLED/releases/download/v0.13.2/soundReactive_WLED_0.13.2_ESP32.bin) but sound-reactive is not working. There is a ICS-43434 microphone connected as following: - SD= GPIO18 - WS= GPIO5 - CK= GPIO19 ![Screenshot](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/2/263b47f3d967c70cf92579654098fcd54d2b2904.jpeg) I there is a WS2813 led strip connected, 45 leds; I selected the “Gravimeter” effect but nothing lights up. At this point I compiled the project from source with " -D MIC\_LOGGER" #define. this is what I read from serial plot: ![serial plot](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/a/a4cc176c62621e9a5e48c712f586879be689d9b0.png) It is really strange, so I also read up the PINs with the oscilloscope: ![scope signal](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/8/89e4e619e854a3e6e13362916c45323b2b7103de.png)\_\_ ![scope zoom](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/0/059b417b9b3681008be4fc988a3559bc4d3e6ae5.png) The signals are OK, so I can’t undersand what is not working. Please, have you got some hints to give me? ---

Be aware that SR is another branch done by others. 😉 ---

Yes, I know. If I’m not wrong, they have not a community forum, and also people that are developing SR WLED are here on this community, that’s why I’m writing here 😌 ---

Some update after lot of tests: I have tried three different ICS-43434MIC and 2 new INMP441 modules. Ultimately, the ICS-43434 is not a working microphone - all the ones I’ve tried only produce noise. On the same PCB with the same firmware and the same settings, the INMP411s work correctly. ![ICS-43434 silence](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/9/9d67f00573a13e72c0d52e2cdfc0761fe70d2d44.png) ICS-43434 in silent room ![ICS-43434 knocking](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/a/a238c896094db813d05765ab8b6b493abcf6fb8a.png) ICS-43434 knocking on the table ![INMP-441 silence](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/b/b8a201cc3043e126baaaca4cd0fec8489ab36b7d.png) INMP441 in silent room ![INMP-441 knocking](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/2/2fff9c3ed06f0ab3b67918d15889122b543146d9.png) INMP441 knocking on the table now my PCB is working fine with INMP441. I hope that this info could be helpful! ---

This is not really good news nor a solution , as i seen some of this discussion on SR discord might be no need to go over the details again , still it would be best if you verify those ICS-43434 mics with bare esp32 as the same mic is mentioned on sr wiki to be working well . If you already verified that three ICS-43434 do not work with SR 13.2 or 14 beta on bare esp32 then please post a link to the source you got those ICS-43434 mics from so we could check with the seller . if you have a faulty mics as you suspect then I hope your first step is to file for a return ---

> [@ALDIY](#): > > still it would be best if you verify those ICS-43434 mics with bare esp32 as the same mic is mentioned on sr wiki to be working well Yes. I did it. I wired the MIC to the ESP32 devkit. I tried 3 of them alternating with INMP441 without changing any config and also reading signals with the oscilloscopes to be sure thath the wiring was good. I bought them from Digikey, it is a certified distributor. Are you using ICS-43434? ---

We were planning to order some ICS-43434 for testing only based on the wiki but if you got an issues with bare esp32 then we might hold on that for a while . we only used INMP441s as we could not find any readily available ICS-43434 on Alie . ---

I’m using some of [these INMP441](https://smile.amazon.com/gp/product/B092HWW4RS), although not for anything particularly much in the way of precision or high quality.
