The ``i2s_audio`` speaker platform allows you to receive audio via the the :doc:`/components/i2s_audio`.
|
|
|
|
This platform only works on ESP32 based chips.
|
|
|
|
.. warning::
|
|
|
|
Audio and voice components consume a significant amount of resources (RAM, CPU) on the device.
|
|
|
|
**Crashes are likely to occur** if you include too many additional components in your device's
|
|
configuration. In particular, Bluetooth/BLE components are known to cause issues when used in
|
|
combination with Voice Assistant and/or other audio components.

# Example configuration entry
|
|
speaker:
|
|
- platform: i2s_audio
|
|
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
|
|
|
|
External DAC
|
|
************
|
|
|
|
- **i2s_dout_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The GPIO pin to use for the I²S DOUT (Data Out) signal.
|
|
- **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 speaker.
