Can't get value

[Lat9898]

Hej I have an issue that it is only working with wrong channel. f.eks. when i set L/R to GND so the channel should be left but it is only working with right channel which is teoritically wrong. and the lowest i get is 75 dBA in a quiet room which is totally wrong.
Do you have any tips that i can do?
I am using INMP441 mic and ESP32 devkitc v4.
Have you had also those issue when u working with Ivan's code.

Yes, there were several reports about L/R channels being swapped (1, 2) Although, it should be already fixed, seems like it still occurs (in some versions of esp-idf?)

There could be various reasons why you are getting wrong values. Unfortunately just final value of 75 dBA doesn't tell much. It requires more debugging e.g. monitoring/printing raw absolute values (hex or decimal) like it was discussed here.
