    Hi,
    I have problem with my ambilight,so I set up everything correctly(I guess).No problems with installation hyperion etc.(I install only from hypercon,not from kodi library).
    So when I play any video,the screen is going to all black,but the ambilight is still working,leds are changing colors.
    I`m using the newest libreelec(9.2.0) and kodi(18.x) and rpi4.In the menu leds are all white,and signal led on arduino are blinking fast.I try to use android app,but leds are not responding too.
    In "get log"

    My arduino sketch:
    /*
    * Arduino interface for the use of WS2812 strip LEDs
    * Uses Adalight protocol and is compatible with Boblight, Prismatik etc...
    * "Magic Word" for synchronisation is 'Ada' followed by LED High, Low and Checksum

    #include "FastLED.h"
    #define NUM_LEDS 33
    #define DATA_PIN 5

    // Baudrate, higher rate allows faster refresh rate and more LEDs (defined in /etc/boblight.conf)

    CRGB leds[NUM_LEDS];

    void setup() {

    FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);
    // Initial RGB flash
    LEDS.showColor(CRGB(255, 0, 0));
    delay(500);
    LEDS.showColor(CRGB(0, 255, 0));
    delay(500);
    LEDS.showColor(CRGB(0, 0, 255));

    Serial.begin(serialRate);
    // Send "Magic Word" string to host
    Serial.print("Ada\n");
    }

    void loop() {
    // Wait for first byte of Magic Word
    for(i = 0; i < sizeof prefix; ++i) {
    waitLoop: while (!Serial.available()) ;;
    // Check next byte in Magic Word
    if(prefix == Serial.read()) continue;
    // otherwise, start over
    i = 0;
    goto waitLoop;
    }
    // Hi, Lo, Checksum
    while (!Serial.available()) ;;
    hi=Serial.read();
    while (!Serial.available()) ;;

    while (!Serial.available()) ;;
    chk=Serial.read();
    // If checksum does not match go back to wait
    if (chk != (hi ^ lo ^ 0x55)) {
    i=0;
    goto waitLoop;
    }
    memset(leds, 0, NUM_LEDS * sizeof(struct CRGB));
    // Read the transmission data and set LED values
    for (uint8_t i = 0; i < NUM_LEDS; i++) {
    byte r, g, b;
    while(!Serial.available());
    r = Serial.read();
    while(!Serial.available());
    g = Serial.read();
    while(!Serial.available());
    b = Serial.read();
    leds.r = r;
    leds.g = g;
    leds.b = b;
    }
    // Shows new values
    FastLED.show();

    }


    Everything working perfect with prismatik on windows.
