SR WLED issue with MIC

I’ve just flashed SR-WLED version 0.13.2 but sound-reactive is not working.
There is a ICS-43434 microphone connected as following:

  • SD= GPIO18
  • WS= GPIO5
  • CK= GPIO19

    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:

It is really strange, so I also read up the PINs with the oscilloscope:


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. :wink:

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 :relieved:
