I2S Audio Media Player
======================
.. seo::
: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 I2S bus. This platform only works on ESP32 based chips.
.. code-block:: yaml

- **dac_type** (**Required**, enum):
2022-06-29 22:29:03 +02:00
- ``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
************
2022-06-29 22:29:03 +02:00
- **i2s_lrclk_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The GPIO pin to use for the I2S LRCLK (Word Select or Left/Right Clock) signal.
- **i2s_dout_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The GPIO pin to use for the I2S DOUT (Data Out) signal.
2022-07-05 09:33:03 +02:00
- **i2s_bclk_pin** (**Required**, :ref:`Pin Schema <config-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.
- ``left``
- ``right``
- ``stereo``
