I2S Audio Media Player

The i2s_audio media player platform allows you to play media from webservers and web streams via the I2S bus. This platform only works on ESP32 based chips.

# Example configuration entry
media_player:
  - platform: i2s_audio
    name: ESPHome I2S Media Player
    dac_type: external
    i2s_lrclk_pin: GPIO33
    i2s_dout_pin: GPIO22
    i2s_bclk_pin: GPIO19
    mode: mono

Configuration variables:

  • dac_type (Required, enum):

    • external: Use an external DAC, for example the NS4168, or UDA1334A.

    • internal: Use the internal DAC

  • All other options from Media Player

External DAC

  • i2s_lrclk_pin (Required, Pin Schema): The GPIO pin to use for the I2S LRCLK (Word Select or Left/Right Clock) signal.

  • i2s_dout_pin (Required, Pin Schema): The GPIO pin to use for the I2S DOUT (Data Out) signal.

  • i2s_bclk_pin (Required, Pin Schema): The GPIO pin to use for the I2S BCLK (Bit Clock) signal.

  • mode (Optional, string): The mode of the I2S bus. Can be mono or stereo. Defaults to mono.

For best results, keep the wires as short as possible.

Internal DAC

  • mode (Required, enum): The channel mode of the internal DAC.
