ESP32 Audio Kit produces no sound despite correct Arduino board settings
03:21 04 Dec 2025

I am trying to do a sound test on the ESP32 Audio Kit, I have tried lots of things but no sound comes out, knowing that when I upload my Arduino code it does nothing until I press the RST button. In Arduino, under tools I have set:

  • Board: ESP32 Dev Module

  • Partition scheme: Huge APP (3MB No OTA/1MB SPIFFS)

  • PSRAM: Disabled

I don't understand what is not working, my headphones are properly connected to EARPHONES, I even tried with a .wav file on an SD card but I think there is an error, the ESP board can't seem to access the card. It's really important, I hope someone can help me.
