'LZeq_1s': Sending state -inf dB with 2 decimals of accuracy

Hi, after i updated esphome a couple of time i decided to reflash the sound_level_meter

but nor im getting only -inf values

[00:16:22][D][sensor:104]: 'LZeq_1s': Sending state -inf dB with 2 decimals of accuracy

[00:16:28][D][sensor:104]: 'LZeq_1s': Sending state -inf dB with 2 decimals of accuracy

i did not change anything else in the yaml. I dont know it its a problem with esphome or something in your code ?!

i tried also the most recent advanced-example-config.yaml you provided, but still gives the same results
cleared cache, rebuilt etc. no luck so far
i also tried to revert back to an older version, but thas not working to, giving error-msg while compiling
anyway probably more useful to figure out whats wrong with the recent code, than to revert back to an older one, i guess

ESPHOME Verizon is 2025.7.5

thnx

I believe the default ESP-IDF version was changed from 4.x to 5.x in the 2025.7.0 release. In earlier ESP-IDF versions, there was a bug where this logic was inverted and didn’t match the microphone’s datasheet. According to the datasheet, connecting the L/R pin to GND should select the left channel. This behavior is now correctly implemented.
