sink_i2s_dac_output_enable
esp_err_t sink_i2s_dac_output_enable(bool enable)
Enable or mute the DAC analog output via the PCM5242 XSMT pin.
Definition sink_i2s_dac.c:20

sink_i2s_dac_get
const audio_sink_t * sink_i2s_dac_get(void)
Get the wired-DAC sink (I2S → PCM5242 → MAX97220 → jack).
Definition sink_i2s_dac.c:85

sink_i2s_dac_init
esp_err_t sink_i2s_dac_init(void)
Bring up the wired path's I2S bus; the sink owns the channel handle.
Definition sink_i2s_dac.c:32

sink_i2s_dac_amp_enable
esp_err_t sink_i2s_dac_amp_enable(bool enable)
Enable or shut down the MAX97220 headphone amplifier via its SHDN pin.
Definition sink_i2s_dac.c:26

audio_sink_t
A PCM output backend (wired I2S DAC or Bluetooth A2DP).
