      For simple outputs like tones, ESP32 enables DAC analogue audio output. The outcome won't be as ideal if you use it to play music, though.

      For simple outputs like tones, ESP32 enables DAC analogue audio output. The outcome won’t be as ideal if you use it to play music, though.

      PWM analogue audio output is supported by the ESP32 and performs marginally better than DAC. On esp-iot-solution, you can get the demo code.

      I2S digital audio output is additionally supported by ESP32. Please refer to the ESP32 Datasheet’s Chapter Peripherals and Sensors for information on I2S adjustable pins.
