    Maybe someone will know something
    esp32 , i2s microphone and 60 SK6812 leds on a strip , 1m power cable 3x0.75, 5V 4A power supply, uploaded WLED audioreactive.

    They respond well to the digital microphone and "flash to the rhythm of the music"

    The problem starts when they light up with a constant colour , they can randomly flash a different colour or change intensity.
    I tested on three different power supplies, I have one driver with one GPIO to handle the LEDs,
    the other driver has two strips and uses two GPIOs. On both it is similar, drivers from ali a ready-made board with a switching power supply for the ESP32 and a switching relay retrofitted only with a level shifter, somewhere I make a mistake because both drivers behave similarly

    controlling the LEDs directly 3.3V from the ESP32 as well as using level shifters from 3.3V to 5V
    models on transistors as well as on the TXS01018E IC

    And how can you be helped when there is not even a word about the uploaded program to the ESP32, let alone its source code.

    at me it flashes rather blue :)
    but there is another problem
    I just started the third board (something like nodeMCU but with esp32-wroom on board) with the TXS01018E level converter , I had still 4 diodes on the strip, played with the soft, connected in the workshop and it works.
    I came to the kitchen, in the furniture strip about 1.5m, cable to this strip 3x0.75

    I started what I had in the workshop but in the kitchen - it still works
    I only connected the control signal from the strip in the kitchen to the strip which I fired up in the workshop and it made disco , and the microphone disconnected

    I don't know if I have such rubbish in the installation or what ? I've been sitting on this for a fortnight now and I'm out of ideas.
