Hey folks.

ESPHome component for PCM5122 DAC is finished. It means that HiFi-ESP32-Plus boards can now be used in Home Assistant/Music Assistant.

So far, it is a basic feature set, namely:

  • DAC startup routine (I2C commands), mainly configuring clock source for 3-wire I2S
  • Digital volume (you know it is much better than software volume, right?), with possibility to set lower and upper bounds.
  • Analog gain (0dB for 2V RMS, and -6dB for 1V RMS output)
  • Mute register, Mute pin (optional)
  • Mixer config: STEREO, LEFT, RIGHT channel. No true MONO at the moment.

As mentioned before, Iā€™m planning to look at internal DSP features next, but it might take more time. This is still the goal, nevertheless

Feel free to share feedback and report a bug!.
