|
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:`config-pin`): 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)*.
|
|
- **mute_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The GPIO pin to use to mute the media player.
|
|
- **mode** (*Optional*, string): The mode of the I²S bus. Can be ``mono`` or ``stereo``. Defaults to ``mono``.
|
|
- **i2s_audio_id** (*Optional*, :ref:`config-id`): The ID of the :ref:`I²S Audio <i2s_audio>` you wish to use for this media player.
|
|
- **i2s_comm_fmt** (*Optional*, string): I2S communication format. By default MSB format is used (AC101, PCM5102A).
|
|
Set to ``lsb`` if using an external DAC that uses Japanese (Least Significant Bit Justified) format (like PT8211).
|
|
Can be ``msb`` or ``lsb``. Defaults to ``msb``.
|
|
|
|
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``
|
