Hello, at first sound reactive 13.4 worked correctly, then it stopped working with the microphone that works with MAX9814, then I observed the output of the microphone with the oscilloscope and I got 1Vdc and the analog signal superimposed, that is, it works fine; From “Peek” I do not get any results, I programmed using the Auduino IDE with the ESPSample test By: Andrew Tuline and I get a signal on the plotter. I suppose then that it is a software error, since I changed the ESP32 Devkit v1 and the microphone system still does not work, the rest works. I have been an electronics professional for 40 years, it is not a lack of experience, if anyone has any idea of the solution, I would appreciate it.
News: I discovered that when I input sound with the AGC on at normal “input level” it adjusts automatically, that is, it receives the signal from the microphone, but the LEDs do not light up.
I use only analog mic. Powered separately 3.3v from the mic and 5v from esp32 and the DC component output from the mic was removed and it does not work.
I placed a nodemcu 8266 with any of the same mic in A0 and it worked perfectly with the version SR_ESP8266_4MB_13b3_withAlexa.bin, with esp32 it does not work with different versions corresponding to esp32, possibly the boards, although I bought them in different stores
P.S. I also experienced silent analog mics depending on the power connection! I have some USB switches (for use with < 2A pixels), when using them, most of the time the analog mics are silent and don’t work - but just sometimes they do work. Without these switches in between analog mics always work. As in the documentation power supply/connection has an influence on WLED analog mic audio experience.
