How to connect the esp32?

[Primus007]

i have successfully wired my pcm5102 to a wemos d1. Now i want to use a ESP32. I have connected: BCK Gpio26 LCK Gpio25 DIN Gpio22 Power: 3,3v + to ESP Vin and DAC VCC 3,3v - to ESP GND and DAC GND

But i hear no sound. please can help anyone?

Using PlayMP3FromSPIFFS example, I changed AudioOutputI2SNoDAC to AudioOutputI2S (include header file, class file name), the wiring just same as your BCK Gpio26 LCK Gpio25 DIN Gpio22 It works for me on ESP32. I used Adafruit UDA1334, but it should works for another I2S DAC module. Good lucks.

I addition, SCK have to be connected to GND

For what it's worth, if the issue is that you get more noise than sound, it could be the bit order. To get my PT8211 to work, I had to change I2S_COMM_FORMAT_I2S_MSB to I2S_COMM_FORMAT_I2S_LSB, here: https://github.com/earlephilhower/ESP8266Audio/blob/d0089c1f4acbcca48ef852400dfdcfd75ff06c8c/src/AudioOutputI2S.cpp#L56 .

Wow, tfry-git you save me hours. I was getting mad testing several pt8211 and a pair of esp32 and noise was horrible. Thank you

How do I make this change on an esp8266?
