It has an ESP32-A1S chip, FCC ID:2AHMR-ESP32A1S.
I was successfully able to get the pipeline_passthru example to work
I also successfully set up squeezelite as a Bluetooth A2DP sink, with audio coming out of the ES8388 DAC.
Now I'm trying to get the pipeline_a2dp_sink_stream example to work, without success.
I only hear crackling noise from the headphones, no music.
The noise changes in volume when I change the music on my phone.
I've set the pin configurations in esp-adf/components/audio_board/lyrat_v4_3/board_pins_config.c to SDA: 33, SCL: 32, BCK: 27, WS: 25, Data Out: 26, Data In: 35.
Please could someone give advice on how to set up the ES8388 chip to output audio?
Thank you!
Peter
