Hello,

For a personnal project, i try to use ESP32 WROOM (devkit1) with a PCM5102 and a SDcard.
I have try to use your examples, but it doesn't work at home...
I try with a MAX98357A and it work perfectly...

I'm going to describe the steps I took:

1/ flash micropython v 1.21 (this works for the other programs I've already done)

2/ connect the PCM with the ESP32 as shown. VIN = 3.3V, GND+SCK = GND, BLK = 32, DIN=33, LCK=25.
I didn't solder any of the jumpers to the board. Was this necessary?

3/I plugged in my earphones

4/ open thonny, copy and paste the code from the example "play_tone.py", save on the board as "test.py" and click on the green button of thonny (to upload and run the programme)

the result is : no sound on the ear phone.
I put the volume_reduction_factor at 1, nothing change...
The programm seem to run correctly, but no sound.

Do i miss a step?
Thank,
A.
