ES8311

The es8311 platform allows your ESPHome devices to use the ES8311 low power mono audio codec. This allows the playback of audio via the microcontroller from a range of sources via Speaker Components or Media Player Components.

The I²C bus is required in your configuration as this is used to communicate with the ES8311.

# Example configuration entry
audio_dac:
  - platform: es8311

Configuration variables

• bits_per_sample (Optional, enum): The bit depth of the audio samples. One of 16bit, 24bit, or 32bit. Defaults to 16bit.
• sample_rate (Optional, positive integer): I2S sample rate. Defaults to 16000.
• use_mclk (Optional, bool): Use the MCLK signal to control the clock. Defaults to True.
• use_microphone (Optional, bool): Configure the codec’s ADC for microphone input. Defaults to False.
• mic_gain (Optional, enum): The gain applied to the ADC microphones. One of MIN, 0DB, 6DB, 12DB, 18DB, 24DB, 30DB, 36DB, 42DB, or MAX. Defaults to 42DB.
• address (Optional, int): The I²C address of the driver. Defaults to 0x18.
• i2c_id (Optional): The ID of the I²C bus the ES8311 is connected to.
• All other options from Audio DAC.
