:description: Instructions for setting up I²S based media players in ESPHome.
:image: i2s_audio.svg
The ``i2s_audio`` media player platform allows you to play media from webservers and web streams
via the :doc:`/components/i2s_audio`. 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_dout_pin: GPIO22
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 :ref:`Media Player <config-media_player>`
External DAC
************
- **i2s_dout_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The GPIO pin to use for the I²S ``DOUT/SDOUT`` *(Data Out)* signal, also referred to as ``SD/SDATA`` *(Serial Data)* or ``DACDAT`` *(Digital to Analog Converter Data)*.
- **mode** (*Optional*, string): The mode of the I²S bus. Can be ``mono`` or ``stereo``. Defaults to ``mono``.
